How is the Earth's atmosphere divided?

What are the different layers of the Earth's atmosphere?

- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
- Exosphere

Answer:

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

The Earth's atmosphere is a complex system that is crucial for supporting life on our planet. It is divided into several layers based on temperature variations and other factors. Understanding these layers is essential for understanding the dynamics of our atmosphere.

Troposphere

The troposphere is the lowest layer of the Earth's atmosphere, where most weather phenomena occur. This layer extends up to about 10-15 kilometers above the Earth's surface and is characterized by a decrease in temperature as altitude increases.

Stratosphere

The stratosphere lies above the troposphere and extends up to about 50 kilometers above the Earth's surface. It is known for containing the ozone layer, which helps to absorb and block harmful ultraviolet radiation from the sun.

Mesosphere

The mesosphere is the third layer of the Earth's atmosphere, located above the stratosphere. Temperatures in this layer decrease with altitude, reaching their lowest point in the mesopause region.

Thermosphere

The thermosphere is the fourth layer of the Earth's atmosphere, characterized by high temperatures due to the absorption of solar radiation. Despite the high temperatures, the thermosphere would feel extremely cold to a human because of the low density of molecules.

Exosphere

The exosphere is the outermost layer of the Earth's atmosphere, blending into outer space. This region is where Earth's atmosphere transitions into the vacuum of space.
