Web1 mrt. 2024 · The mantle is the mostly solid bulk of Earth’s interior. The mantle lies between Earth’s dense, superheated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84 percent of Earth’s total volume. As Earth began to take shape about 4.5 billion years ago, iron and ... The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases. This characteristic is used to define its limits: it begins at the top of the stratosphere (sometimes called the stratopause), and ends at the mesopause, which is the coldest part of Earth's a… WebThe mesosphere is the thinnest layer of the atmosphere, which extends to a height of 85-90 km in height. This layer is very important, since it is the one that stops the small meteorites that crash against the terrestrial sky. how do i return equipment to spectrum
