Question

describe the main feature of the troposphere

Answer 1

The troposphere is the lowest layer of the atmosphere. In this layer, temperature decreases at the rate of 1 degree C for every 165 m ascent. The troposphere is the densest zone of the atmosphere. Three-fourths of the atmosphere is found within 11 km of the surface of the Earth, including most of  the oxygen we need to breathe. The average thickness (altitude or height from the  surface of the Earth) of the troposphere is 13 km. The thickness varies from about 8 km at the poles to 18 km near the equator. The troposphere is also known as the weather-making zone because all physical processes of weather, like wind, clouds, storms, rainfall, mist, fog and hail, occur here.
