A thick gaseous envelope surrounding the earth is called atmosphere. The density of air in the atmosphere varies with altitude. It filters sunlight reaching the earth, affects climate and serves as a reservoir of elements essential for life (eg. oxygen, nitrogen, CO 2 etc.) ..

Atmospheric Refraction - Atmospheric refraction is the shift in apparent direction of a celestial object caused by the refraction of light rays as they pass through Earths atmosphere. The twinkling of stars and variation in size of the Sun are due to atmospheric..

Gas Relative % by Volume Nitrogen (N 2 ) 78.09 Oxygen (O 2 ) 20.93 Argon (A) 00.93 Carbon di oxide (CO 2 ) 0.032 Miscellaneous 0.02 Total 100.000 ..

Carbon Dioxide - During photosynthesis, carbon dioxide is converted into carbohydrates and this is called fixing of carbon dioxide. Many processes like respiration, combustion, volcanic activity, etc. release carbon dioxide into the atmosphere. This carbon dioxide of the atmosphere..

Question: Why does water boil at a lower temperature at higher altitudes? Answer: Boiling occurs at a point where vapour pressure is equal to the external atmospheric pressure. At higher altitudes atmospheric pressure is much less. Less thermal energy is required to g..

The abiotic environment includes the air (atmosphere), water (hydrosphere) and land (lithosphere). The biotic environment includes the plants, animals and the microbe..

Pollution of the atmosphere with industrial gases has been found to result in as much as 15% loss. Soot can block stomata and reduce the transparency of the leaves. Some of the other pollutants are ozone and sulphur dioxide. In fact, lichens are very sensitive to sulphur dioxide in the h..

It is a method by which two or more different crops are grown together in the same soil. A mixed cropping of ragi with pigeon gram replenishes the soil because pigeon gram fixes the atmospheric nitrogen, which goes into the soil in the form of nitrates. These nitrates are utilised by the..

Resources that are unlimited in nature and are not likely to be exhausted by human activities fall under this category. Solar radiation, air, water, precipitation (rainfall, snow fall, etc.,) and atomic power are some instances of such resources. Some of them may undergo temporary imbalances due t..

The rate of transpiration is affected by many factors such as light, temperature, availability of soil water and atmospheric humidity. The plants also show adaptations to reduce transpiration and thereby reduce water loss. For example: Desert plants may not have leaves (stem has photosynt..
