How does mesosphere protect life?

How does mesosphere protect life?

The mesosphere is very important for earth’s protection. 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 vapour in its atmosphere into ice clouds.

Which layer of the atmosphere does life exist?

Troposphere. At the bottom of the atmosphere, where most of the life on the surface exists, is the troposphere. The troposphere is the only atmospheric layer that can support life. The higher layers have filtered out the harmful radiation, and there are large amounts of water vapor.

Where does the mesosphere start in the Earth’s atmosphere?

This picture explains about the mesosphere. The mesosphere is a layer of Earth’s atmosphere. It starts about 50 km (31 miles) above the ground and goes all the way up to 85 km (53 miles) high. The layer below it is called the stratosphere. The layer above it is the thermosphere.

Is the mesosphere a difficult layer to study?

The mesosphere is difficult to study, so less is known about this layer of the atmosphere than other layers. Weather balloons and other aircraft cannot fly high enough to reach the mesosphere. Satellites orbit above the mesosphere and cannot directly measure traits of this layer.

Are there sprites and elves in the mesosphere?

Odd electrical discharges akin to lightning, called “sprites” and “ELVES”, occasionally appear in the mesosphere dozens of kilometers (miles) above thunderclouds in the troposphere below. The stratosphere and mesosphere together are sometimes referred to as the middle atmosphere.

Is the Space Shuttle Endeavour in the mesosphere?

The Space Shuttle Endeavour straddling the stratosphere and mesosphere in this photo. The troposphere, which contains clouds, appears orange in this photo. Diagram showing the five primary layers of the Earth’s atmosphere: exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The layers are to scale.
