Question

How does the mesosphere protect the earth?

Answer 1

The mesosphere protects Earth by preventing meteor impacts. When objects from space enter the atmosphere, the mesosphere is the first dense region of gas they encounter. Most of these objects vaporize or melt when they collide with atmospheric gas particles.

Answer 2

The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface.The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapor in its atmosphere into ice clouds.
