Harmful results of Greenhouse Effect is global warming. While the green house gases enable life to exist, problems arise when the atmospheric concentrations of these gases increase. All climate changes up to the industrial revolution occurred naturally as very few gases were released by ..

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. Howe..

There are two overlapping water cycles operating in nature. 1) Global water cycle 2) Biological water cycle. Global water cycle does not involve life. Water evaporates from water bodies like seas and oceans (more than 75% of total evaporation), lakes and rivers. Condensation of ..

Water - 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..

Excessive production of CO 2 leads to an increase in the concentration of CO in the Earth's atmosphere. This leads to what is known as 'the green house effect'. Simply stated green house effect creates ozone layer depletion or displaces ozone protection from certain areas (or holes) in the Earth'..
