The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normally reflected back into the space. How..

>o F in the next century. But, the entire scientific community was not convinced that global warming was occurring. However, the new data coming in is unsettling. The latest evidence that the earth's climate is getting warmer comes not from theoretical models, but from birds, trees, flowe..

Summary - The basis of life on earth is atmospheric cover on earth and natural cycles like carbon, oxygen, nitrogen and hydrological cycles. Atmosphere is evolved in its present form due to sunlight and rotation of earth on its axis. Many environmental changes like change in rainfall patt..

Water is the only substance that can exist simultaneously in all the three states of matter, i.e., solid, liquid and gaseous on this earth,. A simple experiment shows the existence of all these three states together. Take a glass half packed with ice cubes and cover it. Th..

Dry ice is used to create artificial clouds as special effects, for stage shows, films, discotheques etc. Dry ice is dropped into water; absorbing heat from the water, the solid carbon dioxide sublimes, carrying with it a lot of water vapor. These two together form thick white ..

In the Earth's biosphere, water is essential to all forms of life. Interestingly, it is also the biospheres most abundant compound and a unique substance from the chemical point of view. About 75% of the Earth's surface consists of water. Water is present as either (a) Solid - ice, snow e..

Globally sea levels have risen 4-8 inches over the last century. The high temperatures have already started melting polar ice caps sea icebergs and glaciers. This has released enormous amount of water. Warmer temperatures also heat water and make it expand; thus ocean levels ne..

About 70-73% of earth is covered by water. Water is available in the form of oceans, seas, rivers, lakes, ponds, pools, polar ice caps and water vapour and this forms the hydrosphere. The main component of hydrosphere is water. Water exists in all the three forms i.e., sol..
