Question

Earth's atmosphere is divided into three parts. Proceeding from the Earth's surface in order they are:

Answer 1

The Earth's atmosphere is divided into five layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Step-by-step explanation:

The Earth's atmosphere is divided into five layers.

1. Troposphere: This is the layer closest to the Earth's surface, extending up to about 12 kilometers. It is where most weather events occur, and it is where humans live and breathe.
2. Stratosphere: Above the troposphere, reaching up to about 50 kilometers, is the stratosphere. This layer contains the ozone layer, which protects the Earth from harmful UV radiation.
3. Mesosphere: Going higher, the mesosphere extends from about 50 to 80 kilometers. Meteors burn up in this layer of the atmosphere.
4. Thermosphere: The thermosphere is located between 80 and 700 kilometers above the Earth's surface. It is characterized by very high temperatures but low density of air molecules.
5. Exosphere: Finally, the exosphere is the outermost layer of the atmosphere, extending beyond 700 kilometers. It gradually merges with space.
