What is the coldest part of the atmosphere?
Also know, why is the mesosphere the coldest part of the atmosphere?
The top of the mesosphere is the coldest part of the atmosphere. As you go higher in the mesosphere, the air gets colder. The air is much thinner (less dense) in the mesosphere than in the stratosphere below. There are fewer air molecules to absorb incoming electromagnetic radiation from the Sun.
One may also ask, what is the hottest part of the atmosphere? Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere. Above 124 mi (200 km), the temperature becomes independent of altitude.
Also to know, which layer of the atmosphere is the coldest?
What is the temperature of each layer of the atmosphere?
The mesosphere starts at 31 miles (50 km) and extends to 53 miles (85 km) high. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere, with temperatures averaging about minus 130 degrees F (minus 90 C). This layer is hard to study.
