Detailed explanation-1: -The lower stratosphere is centered around 18 kilometers above Earth’s surface. The stratosphere image is dominated by blues and greens, which indicates a cooling over time. Diagram showing the five primary layers of the Earth’s atmosphere: exosphere, thermosphere, mesosphere, stratosphere, and troposphere.
Detailed explanation-2: -The bottom of the stratosphere is around 10 km (6.2 miles or about 33, 000 feet) above the ground at middle latitudes. The top of the stratosphere occurs at an altitude of 50 km (31 miles). The height of the bottom of the stratosphere varies with latitude and with the seasons.
Detailed explanation-3: -Troposphere means “region of mixing” and is so named because of vigorous convective air currents within the layer. The upper boundary of the layer, known as the tropopause, ranges in height from 5 miles (8 km) near the poles up to 11 miles (18 km) above the equator.
