SOLAR SYSTEM

Detailed explanation-1: -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).

Detailed explanation-2: -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.

Detailed explanation-3: -The Inner Core It is the centre and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel with temperatures up to 5, 500oC.

Detailed explanation-4: -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.

Detailed explanation-5: -The thermosphere is the second-highest layer of Earth’s atmosphere. It extends from about 90 km to between 500 and 1, 000 km.

Detailed explanation-6: -Answer and Explanation: The thermosphere and exosphere are technically the warmest layers because they absorb the shortest wavelengths of solar radiation, heating (and also ionizing) molecules, though this occurs primarily in the thermosphere which is home to much of the resultant ionosphere.
