Question: Meteorites entering the Earth’s atmosphere burn up in which of the following layers?
Options:
Troposphere
Exosphere
Thermosphere
Mesosphere
đŸ”‘Key Points:
-Mesosphere is the layer of the Earth's atmosphere where most meteorites burn up upon entering.
-The mesosphere extends from about 50 to 85 kilometers (31 to 53 miles) above the Earth.
-This layer is characterized by decreasing temperatures with altitude, making it the coldest layer of the atmosphere.
-Meteorites burn up in the mesosphere due to the high density of particles, which causes friction and heat as they enter the atmosphere.
-The mesosphere protects the Earth by preventing most meteorites from reaching the surface.
đŸ”´Additional Information:
-The Troposphere is the lowest layer of the Earth's atmosphere where weather phenomena occur.
-The Stratosphere is above the troposphere and contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.
-The Thermosphere is above the mesosphere and is characterized by high temperatures due to the absorption of high-energy X-rays and ultraviolet radiation from the Sun.
-The Exosphere is the outermost layer of the Earth's atmosphere, gradually transitioning into outer space.
-Each layer of the atmosphere plays a crucial role in supporting life and protecting the Earth from harmful solar radiation and space debris.
