The Earth's atmosphere is divided into several layers based on the variation of temperature with altitude. One of these layers is the thermosphere, which lies above the mesopause, the boundary between the mesosphere and the thermosphere.
The thermosphere is characterized by a significant increase in temperature with altitude. This increase occurs primarily due to the absorption of solar radiation by certain gases present in this region, particularly oxygen and nitrogen. When solar radiation enters the thermosphere, it interacts with these gases, causing them to absorb energy and heat up. This process leads to higher temperatures at higher altitudes within the thermosphere.
Despite the high temperatures, the thermosphere is not perceived as hot in the conventional sense because the atmosphere at such altitudes is extremely thin. The density of molecules in the thermosphere is very low, which means that even though individual molecules are moving rapidly due to their high kinetic energy, there are very few of them to transfer heat to other objects.
It's important to note that the thermosphere is also the region where phenomena such as the auroras occur. Solar particles interact with the gases in the thermosphere, causing them to emit light and produce the stunning displays of the auroras, commonly known as the northern and southern lights.
Furthermore, the thermosphere is the layer where many satellites orbit the Earth. The low density of gas molecules allows satellites to travel with less drag, making it an ideal region for space missions and satellite operations.
In summary, the thermosphere lies above the mesopause and is characterized by increasing temperatures with altitude due to the absorption of solar radiation. Despite the high temperatures, the thin atmosphere at this altitude means that the thermosphere does not feel hot in the conventional sense. It plays crucial roles in phenomena such as the auroras and is essential for satellite operations and space exploration.

Thermosphere:
The thermosphere is the region in the Earth's atmosphere that lies above the mesopause, which is the boundary between the mesosphere and the thermosphere. This region is characterized by increasing temperatures with height, unlike the other layers of the atmosphere where temperatures generally decrease with altitude.
Key Points:
- The thermosphere is where temperatures rise due to absorption of highly energetic solar radiation.
- This region can reach temperatures of up to 2000°C or higher, despite the low density of particles.
- The thermosphere is also where the International Space Station orbits, as the high temperatures are not a concern due to the low density of particles.
In conclusion, the thermosphere is a unique region in the Earth's atmosphere where temperatures increase with height, making it an important layer for understanding atmospheric dynamics and space exploration.
