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 Οκτ 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 km.
The thermosphere is the outermost layer of Earth's atmosphere, extending from about 85 kilometers (53 miles) above the surface to the edge of space at roughly 600 kilometers (373 miles). This layer is characterized by a significant increase in temperature with altitude, primarily due to the absorption of high-energy solar radiation.
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.
The thermosphere is defined as the second-highest layer of the Earth's atmosphere, extending from the mesopause to the thermopause, characterized by high temperatures influenced by solar activity and molecular diffusion leading to gravitational separation of species.
