Final answer:

The thermosphere is the layer of the Earth's atmosphere that starts above the mesosphere and extends to 600 kilometers high. It has a high relative temperature and contains subcategory layers such as the ionosphere and exosphere. In the thermosphere, you can find objects such as satellites and witness auroras.

Step-by-step explanation:

The thermosphere is the layer of the atmosphere that starts just above the mesosphere and extends to 600 kilometers (372 miles) high. It is one of the five layers of the Earth's atmosphere, with the others being the troposphere, stratosphere, mesosphere, and exosphere.

The relative temperature of the thermosphere is extremely high, reaching up to 2000 degrees Celsius (3600 degrees Fahrenheit) due to the absorption of high-energy solar radiation.

The thermosphere can be further divided into subcategory layers, including the ionosphere and the exosphere.

The ionosphere is an abundant layer of electrons and ionized atoms and molecules that extends from about 48 kilometers (30 miles) above the surface to the edge of space at about 965 kilometers (600 miles).

It plays a crucial role in Sun-Earth interactions and enables radio communications. The exosphere is the upper limit of the atmosphere and extends from the top of the thermosphere up to 10,000 kilometers (6,200 miles) above sea level.

In the thermosphere, you will find various objects such as satellites, which orbit the Earth at this altitude. Additionally, the thermosphere is where auroras occur, as charged particles from the Sun collide with gas molecules in this layer, creating colorful light displays.
