atmospheric co2 increase

High humidity means high water vapour pressure outside and it results in lower rate of transpiration and as the humidity decreases rate of transpiration increases..

The atmosphere is the layer of air around the earth. It extends up to 1000 km above the surface of the earth and has a total weight of 4.5 10 1 8 kg (i.e., five million billion tons). This weight exerts a pressure on the surface of the earth which is called atmospheric press..

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 refraction of starlight. Twin..

Pollution Due to the Burning of Fossil Fuels (Additional) - Contamination of air with harmful toxic gases, smoke and particulate matter (e.g., dust etc.) is called air pollution. The substances that cause pollution are called pollutants. Combustion of fossil fuels is one of the main causes of pollu..

Presence of Carbon Dioxide in Air - Another important constituent of air is carbon dioxide. As stated before, plants use it to synthesize carbohydrates, a basic food for all of us. It is also one of the green house gases that help to retain the warmth of the ..

It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its great a..
