SOLAR SYSTEM

Detailed explanation-1: -The mesosphere is directly above the stratosphere and below the thermosphere . It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth’s atmosphere, about-90° C (-130° F), are found near the top of this layer.

Detailed explanation-2: -Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).

Detailed explanation-3: -Mesosphere. The temperature in the mesosphere grows colder with the altitude. This is because there are few gas molecules in the mesosphere to absorb the Sun’s radiation. The only heat source is the stratosphere below.

Detailed explanation-4: -The thermosphere is above the mesosphere but is actually the hottest layer due to the absorption of intense x-rays and ultraviolet radiation. Thus, the mesosphere lacks radiation absorption from below and above, making it the coldest layer.

Detailed explanation-5: -The thermosphere lies between the exosphere and the mesosphere. “Thermo” means heat, and the temperature in this layer can reach up to 4, 500 degrees Fahrenheit. If you were to hang out in the thermosphere, though, you would be very cold because there aren’t enough gas molecules to transfer the heat to you.

Detailed explanation-6: -The coldest layer of atmosphere is the mesosphere while the hottest layer of the atmosphere is thermosphere.

Detailed explanation-7: -Very cold temperatures-the mesosphere is the coldest layer, and the exosphere can get as cold at night if solar activity is low, since that is the only mechanism by which it is heated.
