GEOLOGY

Detailed explanation-1: -These layers starting from the Earth’s surface are called the troposphere, the stratosphere, the mesosphere, the thermosphere and the exosphere.

Detailed explanation-2: -These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.

Detailed explanation-3: -Earth’s atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere.

Detailed explanation-4: -The troposphere starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region.
