How to control water pollution at home

2011-12-08T09:53:00.000-08:00

Water pollution at point source can be reduced by legislation and to prevent water pollution from non-point source is difficult due to absence of proper policies and strategies.
Sewage treatment is must before it released into water by physical method-sedimentation and filteration for removing large and suspended particles. Then by secondary treatment - to promote bacteria treatment which leads biological oxidation carried out in oxidation pond and biosolid get formed. Tertiary Treatment - pathogens. metals are removed by strong oxidins agents like chlonn gas, ozone gas and then waste water is discharged into natural water or used for irrigation
Industrial hot water should be cooled when released from power plants or from industrial plants
Washing clothes and taking baths in tanks or wells from where supply of drinking water is made at should be strictly prohibited
Acids and alkali's tan be neutralized before releasing into water i e acids by allele stone and Alkalies by CO. sulpharic acid
Metalic salts can be precipitated before releasing.

Causes of Marine AND sea water pollution.

Through out the world oceans and seas all are treated as the dumping grounds or links for the disposals of urban waste.
1 ) Main sources of mine water pollution are rivers. Most of the major rivers have discharge into water bodies.

2 ) Heavy metals like mercury, copper nickel, cadmium oxidesof iron all are discharged from various industrial units through river channel or in the form of point source of direct discharge pollute ocean water, It is estimated that every year 5000 tonnes of mercury add into oceans, seas and bays.

3 ) Seas are also used to dump radionucleide waste store in large A containers and dumped in deep seas considering that it is a better disposal site.

4 ) rivers from catchment and basin area bring various polloutants and finally pour into sea which Includes synthetic Po detergencagrochemicals. solid wastes and plastic materials.

5) Drilling of oil welts on cream floor where oil spilling is common. leads marine water pollution.

Soil Testing for Home Garden

2011-11-09T18:21:00.002-08:00

Soil Testing: "Plants need the right nutrients for their growth and these nutrients are absorbed from the soil in which they grow. Often times though the soil may lack the exact nutrients needed by the plant and so it is necessary to provide these by way of fertilizers. The thing is you need to know the soil composition, so you know exactly how much or how little fertilizer to add. Too much can harm the environment and too little won't have much effect on plant growth.

To effectively know how much fertilizer is required, samples of the soil are taken and tested in a laboratory. This is known as soil testing."

Tree Roots Effects on Soil

2011-11-09T18:21:00.001-08:00

Tree Roots Effects on Soil: "The roots affect the soil, depending on the type of the tree and the soil. These effects have a direct impact on all the plants grown near the tree. Normally a healthy tree represents healthy soil. A big tree takes up most of the water available in the soil, leaving the other plants dry. Growing as well as mowing lawn grass is another difficulty around a large tree, especially if the roots are protruding outside. Tree roots help control soil erosion, however in some cases the roots have a negative effect on the soil by causing a phenomenon called allelopathy.

Organic Soil Mix

2011-11-09T18:21:00.000-08:00

Organic Soil Mix: "A good organic soil mix is very essential for the healthy growth of your plants. Organic gardening has regained its popularity since ancient times, when that was the only option people had. The reason being that through this method you can have a control over what you are consuming. Vegetables and fruits bought from the market do not hold any guarantees about being safe to consume. Harsh chemicals such as fertilizers and pesticides have become an inseparable part of agriculture, these chemicals indirectly enter our systems and cause fatal harm. Here we will discuss how to make organic soil mix at home.

How to Make Humic Acid

2011-11-09T18:20:00.001-08:00

How to Make Humic Acid: "You can either extract humic acid from a humus rich soil sample, from peat moss or from humic compost. If you regularly add humic compost to your garden then sourcing humic acid from both humus laden soil or the organic compost would be easy, though quite tedious. Extracting humic acid from peat or peat bogs can be even more taxing if neither are available within close vicinity of your garden. Anyway, let's go along the relatively simpler, but equally time-consuming route and find out how humic acid can be extracted from garden soil to which humic compost is added on a regular basis.

How to Improve Clay Soil

2011-11-09T18:20:00.000-08:00

How to Improve Clay Soil: "Fill 2/3 of the jar with clean water. Now take the soil, place it inside the jar and close the lid tightly. Give it a vigorous shake for a minute or two. See that the soil has broken down at the bottom of the jar. Allow it to settle down for approximately an hour. The sand layer which is the heaviest will settle at the bottom. The silt layer is at the next level and finally it is the clay layer which will be at the top. The condition of the soil is determined by the percentage of each layer. If the soil has 50 to 100 percent clay then it is clay soil.

So, how will you combat the clay soil problem in your yard? Though clay soil is capable of retaining a good amount of moisture and essential nutrients, it may cause a number of problems for the gardener"

Soil Pollution Causes and Effects

2011-11-09T18:19:00.001-08:00

Soil Pollution Causes and Effects: "Decrease in soil fertility and therefore decrease in the soil yield. Definitely, how can one expect a contaminated soil to produce healthy crops?
Loss of soil and natural nutrients present in it. Plants also would not thrive in such a soil, which would further result in soil erosion.
Disturbance in the balance of flora and fauna residing in the soil.
Increase in salinity of the soil, which therefore makes it unfit for vegetation, thus making it useless and barren.
Generally crops cannot grow and flourish in a polluted soil. Yet if some crops manage to grow, they would be poisonous enough to cause serious health problems in people consuming them.
Creation of toxic dust leading is another potential effect of soil pollution.
Foul smell due to industrial chemicals and gases might result in headaches, fatigue, nausea, etc. in many people.
Soil pollutants would bring in alteration in the soil structure, which would lead to death of many essential organisms in it. This would also affect the larger predators and compel them to move to other places, once they lose their food supply."

Facts about Land Pollution

2011-11-09T18:19:00.000-08:00

Facts about Land Pollution: "Land pollution is the result of human misuse of soil. Poor agricultural practices, digging up of important resources and dumping of garbage underground can cause land pollution. Urbanization, the growth of rural lands into urban areas and industrialization that results in the formation of an industrial society are regarded as the two main causes of land pollution.

The excavation of minerals, the increasing quarrying and mining activities lead to land pollution. The excavation and mining activities lead to the loosening of soil. Increased mechanization leads to the contamination of soil, thus causing severe land pollution.

Deforestation is one of the major causes of loosening of soil, that in turn causes soil erosion. The soil that is left naked on harvesting crops from agricultural lands is vulnerable to being eroded by wind and water. Intensive agricultural practices cause the soil cover to lose its nutritional elements, making it of no use for agriculture."

Facts about Soil Pollution

2011-11-09T18:18:00.001-08:00

Soil Pollution Facts: "Soil is a non-renewable resource with more potential to degrade. According to the study published by the European Commission in April 2002, among other major threats to soil, decline in organic matter and contamination needs immediate attention. One of the most severe complications of soil pollution facts is that the chemicals from the soil will contaminate the crops grown on them, and also the groundwater that is used for drinking. The same contaminated soil also has the potential to seep into large water bodies and have an effect on the overall eco-system, thus, becoming a major environmental issue.

Land Pollution 2011

2011-11-09T18:18:00.000-08:00

Land Pollution: "Solid Waste: Semisolid or solid matter that are created by human or animal activities, and which are disposed because they are hazardous or useless are known as solid waste. Most of the solid wastes, like paper, plastic containers, bottles, cans, and even used cars and electronic goods are not biodegradable, which means they do not get broken down through inorganic or organic processes. Thus, when they accumulate they pose a health threat to people, plus, decaying wastes also attract household pests and result in urban areas becoming unhealthy, dirty, and unsightly places to reside in. Moreover, it also causes damage to terrestrial organisms, while also reducing the uses of the land for other, more useful purposes.

Southern Tip of Greenland: "The southern tip of Greenland is seen in this high-oblique, almost colorless, stark photograph of the worlds largest island. The blackness of space contrasts sharply with the whiteness of clouds, ice, and snow. The only true color is the blue of the Atlantic Ocean and the Labrador Sea. Cloud-free conditions existing along the southern coastal area emphasize the deeply indented fjords along the coast. A close look at the white areas reveals three different features-snow and ice on the land; cloud formations over the central region and the eastern and western sides of the island; and wispy-looking ice floes off the southeast and the southwest tip of the fjord-lined coast"

From the La Silla Observatory in the mountains of Chile, Naef and his colleagues have stolen glimpses of the dance for months. But for much of that time their view was blocked by clouds, a foot of snow, and, this August night—midwinter in Chile—humidity so high that the telescope dome had to be shut to keep out frost. Earlier in the evening, between cups of espresso and cigarette breaks, Naef gloomily eyed a display of weather data. He feared another lost night.

Moons, Rings, and Magnetospheres

2011-11-09T18:11:00.000-08:00

Solar System, Solar System Information, Facts, News, Photos -- National Geographic: "Moons, Rings, and Magnetospheres

There are 140 known natural satellites, also called moons, in orbit around the various planets in our solar system, ranging from bodies larger than our own moon to small pieces of debris.

From 1610 to 1977, Saturn was thought to be the only planet with rings. We now know that Jupiter, Uranus, and Neptune also have ring systems, although Saturn's is by far the largest. Particles in these ring systems range in size from dust to boulders to house-size, and may be rocky and/or icy.

Most of the planets also have magnetic fields, which extend into space and form a magnetosphere around each planet. These magnetospheres rotate with the planet, sweeping charged particles with them. The sun has a magnetic field, the heliosphere, which envelops our entire solar system. "

Coldest Place on Earth

2010-07-23T02:59:00.000-07:00

The Antarctica is recorded to be the coldest place on Earth since long time and is still unbeatable. located in Antarctica, is the current coldest place on Earth with the lowest temperature ever recorded. Antarctica is a fifth-largest continent located in the southernmost tip of the Earth. It is also known as the continent of extremes as it is the coldest and the windiest place on Earth. The Antarctica lies on about 2000 meters above the sea level which makes it the highest continent on Earth.

The Antarctica receives very little rainfall every year and hence, can be categorized as a desert. It is not owned by any other country in the world which makes it approachable for people (scientists) all over the world. human encroachment due to several reasons; the foremost being its inaccessibility. the other hand, extremely low temperature, lack of resources, food, shelter, etc. makes it an alien land for human beings, even today. However, due to advancement of technologies. As nearly 90% of the ice in the world is found in Antarctica, we find seas, mountains and lands covered with solid ice for the entire year. Read more on Antarctica facts.

Temperature of Coldest Place on Earth
As mentioned above, Vostok in Antarctica is the coldest place on the Earth with the lowest temperature recorded as -89.2°C or -128.6°F or 183 Kelvin. It is even believed that at some times, the temperature fell as low as -91°C or -131.8°F or 181 Kelvin. However, there is no official record that proves the latter temperature readings. The average temperature recorded in summer in Vostok, Antarctica is -27.5°C or -17.5°F while the hottest or the warmest temperature recorded in summer was -19°C or -2.2°F or 254 Kelvin.

Which is Bigger the Earth or the Sun

2010-07-23T02:54:00.000-07:00

The Earth and the Sun
The Sun is a star located at the center of the Solar System in the Milky Way galaxy. The eight planets of the Solar System revolve around the Sun, and planet Earth is just one of them. Also known as the Blue Planet, the Earth is the 5th largest planet in the Solar System, with a diameter of around 7926 miles (12,755 km). Though this number may make the planet look massive, it is negligible as compared to the Sun, which constitutes around 99.86 percent of the total mass of the Solar System. Add to it the fact that the Sun is just a medium sized star, and there are several stars which are several times bigger than it, and you realizes that our planet is just a minute object in the Universe. In simple words, the Sun is bigger than the Earth, but a look at the details of their size will provide you with some of the most interesting facts about the Sun.
Which is Bigger the Earth or the Sun?
Coming back to how big are Earth and Sun, let's get into the details of the size of these two. The equatorial radius of planet Earth is 6,378.1 km, while its polar radius is 6,356.8 km, which eventually amounts to a mean radius of 6,371.0 km. The equatorial radius of the Sun, on the other hand, is 6.955 × 10⁵ km, and therefore the mean diameter of the solar body amounts to a whopping 1.392 × 10⁶ km. Simply speaking, the diameter of the Sun is 864,938 miles, which makes it a 109 times bigger than Earth. Similarly, the volume of the Earth is 1.08321 × 10¹² km³, while the volume of the Sun is 1.412 × 10¹⁸ km³. Simply put, the volume of the Sun is 1,299,400 times bigger than the volume of the Earth. This, in turn, means that you can fit in around 1,300,000 Earths inside the Sun with ease.

That answered one of the most simple question in the field of astronomy - which is bigger, the Earth or the Sun? Even though the Moon and the Sun appear to be of the same size to the naked eyes, the Sun is 400 times bigger than the Moon, which has a radius of 2,160 miles. The distance from the Earth to Sun is around 93,000,000 miles, while the same from the Earth to the Moon is 238,857 miles. It is this difference in the distance which makes the Sun and the Moon appear to be roughly of the same size. At the end of the day the relative size of the Earth, Jupiter and the Sun can be represented as 1:10:100, which means that planet Jupiter is 10 times as big as the Earth, and the Sun is a 100 times as big (109 times to be precise) as the Earth.

Distance from Earth to Moon

2010-07-23T02:50:00.000-07:00

The Moon which revolves around the Earth is the fifth largest of all moons present in our solar system. Its diameter is 3,474 km and is slightly greater than a quarter of the Earth's diameter. The total surface area of moon is less than 10% of Earth's surface area. The gravity experienced on the surface of moon is 17% of the Earth's gravitational force. transfer of kinetic energy which takes from the Earth to the moon is the reason behind this slowdown. on the surface of Earth. effect of this gravitational interaction on the moon is seen in the form of its orbit being raised. Information about the distance from the Earth to the Moon is provided in the following paragraphs. Read more on facts about moon.

What is the Distance from the Earth to the Moon
moon revolves around Earth in an elliptical orbit. distance between the Earth and moon thus, fluctuates or changes at certain points. apogee is a position at which the moon is farthest from the Earth, while the perigee is the closest distance. At the perigee, the total distance between the Earth and moon is 363,300 km; while at the apogee the distance increases up to 405,500 km.

Average Distance From Earth to Moon
The average distance from the Earth to the moon in km. is 384,400. This distance accounts for 30 times the Earth's diameter. It would take around 16 days to reach the moon from the Earth at a speed of 1000 km/hr. Passenger jets are capable of attaining this speed.

Distance from Earth to Moon in Meters
distance from the Earth to the Moon point is 363,104,000 meters. At apogee, this distance increases up to 405,696,000 meters. The average distance is 384,400,000 meters.

Distance from Earth to Moon in Miles
The total distance from the Earth to the Moon in miles is 238,857. It is the average distance between this satellite-planet pair.

Distance from Earth to Moon in Feet
In countries where feet is the common unit of measurement, would prove to be helpful. The distance between the Earth and moon at apogee and perigee is 1,331,020,000 feet and 1,191,290,000 feet respectively. The average distance is 1,261,000,000 feet.

Distance from Earth to Moon in Light Years
The distance present between the moon and the Earth in terms of light years is calculated with the help of speed of light in vacuum. As stated earlier the distance between the moon and Earth is 384,400 km, i.e. 3.844x10^8 m. The speed of light in vacuum is 3x10^8 m/s. distance from Earth to Moon in Light years is therefore, calculated by the formula,
