Question

write briefly about the layers of the atmosphere​

Answer 1

Answer:

the atmosphere is comprised of layers based on temperature .this layers are the troposphere, stratosphere, mesosphere and thermosphere .A further region at above 500 km above the earth's surface is called ecosphere.

Answer 2

Answer:

The atmosphere of the earth is a mixture of gases that surrounds the planet. By shielding our planet from the sun's harmful UV rays, the atmosphere plays a crucial role in making life possible on Earth.

Our atmosphere contains a variety of gases such as nitrogen, oxygen, and carbon dioxide. Each gas has its own chemical make-up. About 78 percent of the gas is nitrogen, 21% is oxygen, and the remaining 1% contains all other gases.

Explanation:

Troposphere, Stratosphere, Mesosphere, and Thermosphere are the four layers of the atmosphere, labeled from low to high classification.

• The troposphere is the first layer of the Earth's atmosphere, extending up to 10–15 kilometres above the surface. As you ascend into the troposphere, the temperature continues to drop. More than 75% of the total mass of the atmosphere is found in the troposphere. At the equator, the troposphere is wider than at the poles.
• The stratosphere is the second layer of the earth's atmosphere, extending up to 15–45 kilometres above the surface. This layer contains the ozone layer. The stratosphere is cooler at the bottom, but as the body ascends into the stratosphere, the temperature climbs steadily.
• Mesosphere layer is located just above the earth's surface and extends up to 50–80 kilometres above it. It is a frigid layer because as altitude increases, temperature decreases. Sounding rockets or rocket-powered aircraft are the primary means of accessing this tier.
• The thermosphere is the layer above the mesosphere that extends from 80 kilometres above the earth's surface to outer space. It's a scorching layer, with temperatures reaching thousands of degrees.
