Which is the highest layer of the atmosphere in which Meteors burn up after entering Earth's atmosphere?

The correct answer is Mesosphere.

• Mesosphere:
  • This is the highest layer of the atmosphere in which the gases are all mixed up rather than being layered by their mass.
  • Meteors burn up in this layer after entering Earth's atmosphere and before reaching Earth's surface.
  • The meteors make it through the exosphere and thermosphere without much trouble because those layers don’t have much air. 
  • But when they hit the mesosphere, there are enough gases to cause friction and create heat.

Additional Information

• Troposphere:
  • The troposphere is the innermost layer of Earth’s atmosphere.
  • This layer gets its name from the weather that is constantly changing and mixing up the gases in this part of our atmosphere.
  • This layer has the air we breathe and the clouds in the sky. 
• Stratosphere:
  • The stratosphere is located above the troposphere and below the mesosphere.
  • There are no storms or turbulence here to mix up the air, so cold, heavy air is at the bottom and warm, light air is at the top. 
  • The ozone layer found in this stratosphere helps protect us from ultraviolet radiation (UV) from the sun by blocking UV radiations from reaching the Earth’s surface.
  • The ozone layer absorbs most of the UV radiation sends to us by the sun.
• Thermosphere:
  • The thermosphere is located above the mesosphere and below the exosphere.
  • The thermosphere is home to the International Space Station as it orbits Earth.
