The mesosphere is the coldest region of Earth’s atmosphere, close to -100°C. It’s the layer of the atmosphere where meteors burn up into small fragments of dust.

80 - 100 km absorbs UV and x-ray radiation least dense layer temperature increase with height auroras occur here Mesosphere 50 - 80 km coldest layer most meteors burn up here temperature decreases …

The mesopause, at an altitude of 80–90 km (50–56 mi), separates the mesosphere from the thermosphere —the second-outermost layer of Earth's atmosphere. On Earth, the mesopause nearly …

Nov 26, 2025 · The coldest layer where meteors typically begin to burn up is the mesosphere. This atmospheric layer is characterized by extremely low temperatures and increasing atmospheric …

May 21, 2024 · The mesosphere begins approximately 30 miles (48.2 km) above the surface of the earth and extends to approximately 50 miles (80.4 km). This layer is where most meteors burn up.

The mesosphere is a layer within the Earth's atmosphere that extends from about 50 kilometres height (above the stratosphere) and about 90 kilometres (below the thermosphere). Like tropospheric …

Most meteors burn up in the mesosphere. A type of lightning called sprites sometimes appears in the mesosphere above thunderstorms. Strange, high-altitude clouds called noctilucent clouds sometimes …

Most meteors vaporize in the mesosphere. Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms.

The thermosphere's atoms and molecules absorb the most heat from the sun. The molecules in the last layer move really fast (temperature = how much molecules move) but they are really far apart from …

It is Earth’s coldest atmospheric layer and the region where meteoroids and space debris burn up. Although our atmosphere looks like one continuous piece of sky, it is made up out of five distinctly …
