how does the mesosphere protect the earth
The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.Temperature decreases with height throughout the mesosphere.The coldest temperatures in Earth's atmosphere, about -90Â° C (-130Â° F), are found near the top of this layer.The boundary between the mesosphere and the thermosphere above it is called the mesopause.emperature decreases with height throughout the mesosphere.
