Detailed explanation-1: -Troposphere. Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.

Detailed explanation-2: -Fifty percent of the total mass of the atmosphere is located in the lower 18, 000 ft of the troposphere. Nearly all atmospheric water vapor or moisture is found in the troposphere, so it is the layer where most of Earth’s weather takes place.

Detailed explanation-3: -Weather systems develop and exist in the troposphere (the lowest layer of the atmosphere). Above this layer lies the stratosphere, which, as the name implies, is highly stratified, stable and dry. It is not directly involved in the development of daily weather.

Detailed explanation-4: -The troposphere is, on average, the warmest part of the atmosphere primarily because the atmosphere is heated from the surface. The atmosphere is highly transparent to solar radiation, but the majority of this radiation is absorbed by Earth’s surface, which heats the troposphere primarily via convection.

Detailed explanation-5: -Option a: Troposphere is regarded as the most important layer of atmosphere. It is the lowermost layer of the atmosphere and contains 75% of all air in the atmosphere. Most clouds occur in this layer because 99% of the water vapour in the atmosphere is found here.
