B) region of the magnetosphere that contains trapped high-energy charged particles. C) intermediate atmospheric layer,in which ultraviolet light from the Sun is absorbed by ozone (O₃)molecules. D) layer of molten iron and nickel below the mantle in Earth's interior.

Question

Quizplus · Accepted Answer

Earth's thermosphere is the outermost atmospheric layer, where ultraviolet light from the Sun is absorbed by nitrogen and oxygen atoms, stripping them of one or more electrons. This process is known as ionization, and it creates the ionosphere, which is important for radio communication and navigation. The thermosphere extends from about 80 km to the edge of space, where it transitions into the exosphere. The temperature in the thermosphere can reach up to 2,000°C due to the absorption of solar radiation.
