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.

Why is the thermosphere hot?
While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the earth. As such, incoming high energy ultraviolet and x-ray radiation from the sun begins to be absorbed by the molecules in this layer and causes a large temperature increase.

Is thermosphere so hot?
The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).

Is the thermosphere the coldest layer?
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.

Can you freeze in the thermosphere?
Even though temperatures can reach several thousands of degrees, the low density of air can make people freeze in the thermosphere.

What is the coldest atmosphere layer?
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).

Why is thermosphere the coldest layer?
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. This also means there aren’t enough molecules for sound waves to travel through. This layer of Earth’s atmosphere is about 319 miles (513 kilometers) thick.

Is the thermosphere colder than the mesosphere?
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.

Why is the thermosphere so hot but feels cold?
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.

Why thermosphere is hot and mesosphere is cold?
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.

Why thermosphere is the hottest layer and not exosphere?
In this layer, UV rays cause ionization and the temperature increases with altitude here due to absorption of solar radiation, making it the hottest. We can understand from the above discussion that the thermosphere has the highest level of absorption of high energy solar radiation, making it the hottest.

Why would you freeze in the thermosphere?
The heat that won’t keep you warm 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. This also means there aren’t enough molecules for sound waves to travel through.

Would you burn or freeze in the thermosphere?
As NASA explains it, if a human were to be in the thermosphere, they “would be very cold because there aren’t enough gas molecules to transfer the heat” into the body (here).

How cold can the thermosphere get?
Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher. The boundary between the thermosphere and the exosphere above it is called the thermopause. At the bottom of the thermosphere is the mesopause, the boundary between the thermosphere and the mesosphere below.

Which layer is coldest to space?
Mesosphere, altitude and temperature characteristics The top of the mesosphere is the coldest area of the Earth’s atmosphere because temperature may locally decrease to as low as 100 K (-173°C).

Is the thermosphere actually hot?
Even though temperatures can reach several thousands of degrees, the low density of air can make people freeze in the thermosphere. The conditions are not suitable for humans to survive but are very suitable for the aurora to be born.
