The thermosphere is the layer of Earth's atmosphere above 80 km where ultraviolet radiation causes photoionization of molecules and creates ions. It is part of the ionosphere and has high temperatures, low density, and variable composition depending on solar activity and altitude.
11 paź 2024 · The thermosphere is a layer of Earth’s atmosphere that can reach up to 4,500 degrees Fahrenheit. Learn about its location, thickness, and what happens in this layer of space.
The thermosphere is a layer of Earth's atmosphere that extends from 90 km to 1,000 km above the surface. It is influenced by solar activity, has low air density, and hosts the aurora and the ionosphere.
Thermosphere, region of increasing temperature in Earth’s atmosphere that is located above the mesosphere. The base of the thermosphere (the mesopause) is at an altitude of about 80 km (50 miles), whereas its top (the thermopause) is at about 450.
The thermosphere is the layer of Earth's atmosphere that borders outer space. It has a very low density, high temperature and varies in altitude from 80 to 1000 km. Learn about its layers, phenomena, composition and the Karman Line.
Definition. The thermosphere is the layer of Earth's atmosphere that lies above the mesosphere and below the exosphere, extending from about 85 kilometers (53 miles) to 600 kilometers (373 miles) above sea level.
2 paź 2019 · Learn about the five major layers of Earth's atmosphere, from the troposphere to the exosphere, and their characteristics and functions. The thermosphere is the third layer, where temperatures increase with altitude due to the low density of molecules.
