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: -Troposphere. Known as the lower atmosphere, almost all weather occurs in this region. The troposphere begins at the Earth’s surface, but the height of the troposphere varies.

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: -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-5: -This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen.
