Question

1. Meteorites burn up in the mesosphere but not in the thermosphere. It is due to

• A. relatively thicker atmosphere in the mesosphere
• B. relatively thicker atmosphere in the thermosphere
• C. very low temperature in the mesosphere
• D. very low temperature in the thermosphere

Answer 1

The correct option is A

relatively thicker atmosphere in the mesosphere

Explanation:

• Meteorites are formed when two asteroids collide with each other and break into small pieces.
• The pieces that are formed after the collision is called a meteorite.
• The size of a meteorite might vary from less than a gram to tons.
• The layer which extends up to about 85 km above the surface of the earth is called the mesosphere.
• Meteorites burn up in this layer due to the presence of a relatively thicker atmosphere.

Hence, option (A) is the correct answer.
