Why don't all molecules in the atmosphere fall into the Earth like an apple falling from a tree?

Options

  1. ABecause molecules are not affected by gravity.
  2. BDue to the random thermal motion causing their velocity to be non-vertical.
  3. CMolecules in the atmosphere are too small to be affected by gravity.
  4. DMolecules are repelled by the Earth's gravitational force.

Correct answer

B. Due to the random thermal motion causing their velocity to be non-vertical.

Step-by-step solution

Correct Option is : (B) Due to the random thermal motion causing their velocity to be non-vertical.
