Atmospheric layers >> Troposphere
The troposphere is the region within the atmosphere between the earth's surface and the tropopause that is centred at an altitude of about 8-15 kilometres.
This region is characterized by decreasing temperature with increasing altitude. The study of the troposphere is very important because we breathe the air in this layer of air.
The troposphere contains about 85% of the atmosphere’s total mass. Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.
The chemical composition determines the air quality. Certain components, even if they are only present in small amounts, may harm health and vegetation.
Therefore, it is of utmost importance to understand how the activities of humans influence the troposphere.
