What Is the Thermosphere, How Cold and High Is the Thermosphere, and What Does Thermosphere Mean In Greek?

The thermosphere is the biggest layer of the earth’s atmosphere and is located above the mesosphere and below the exosphere.

Ultraviolet radiation causes ionization in the thermosphere.

The thermosphere is located from about 80 kilometres (50 mi) to 500 kilometres (310 mi) above the earth’s surface.

Temperatures rise in the thermosphere because of the presence of gas and particles that absorb the Sun’s rays.

In fact, the temperature in the thermosphere can reach 1,500 °C (2,730 °F) during the day.

The word thermosphere comes from the Greek word “thermos”, which means heat.

The International Space Station has a stable orbit in the middle of the thermosphere, at about 320 kilometres (200 mi) above the earth.
