What is the order of the earths atmosphere from the earth to the sky?
troposphere, stratosphere, mesosphere, thermosphere, exosphere
The order of Earth’s atmosphere from the Earth to the sky can be divided into five main layers:
1. Troposphere: This is the lowest layer of the atmosphere and extends from the Earth’s surface up to about 7 to 20 kilometers above the surface. It is where we live, and where almost all weather occurs. The air in the troposphere is densest at the bottom and gets gradually thinner (less dense) as altitude increases.
2. Stratosphere: This layer lies just above the troposphere and extends from 20 to 50 kilometers above the Earth’s surface. The ozone layer, which absorbs harmful UV radiation from the sun, is found in this layer.
3. Mesosphere: This is the third layer of the atmosphere and lies above the stratosphere, from 50 to 85 kilometers above the Earth’s surface. This is the coldest layer of the atmosphere, with temperatures as low as -90 degrees Celsius.
4. Thermosphere: This layer begins at an altitude of about 85 to 600 kilometers above the Earth’s surface. Temperatures in this layer can reach thousands of degrees Celsius because it is where solar radiation ionizes the gases in the atmosphere.
5. Exosphere: This is the outermost layer of the atmosphere, and it extends from the top of the thermosphere to about 10,000 km above the Earth’s surface. This layer is very thin and contains very few particles. It gradually fades into the vacuum of space.
