Answer

Brief Explanations:

  • Air density decreases with altitude, so air is less dense on a mountaintop than at sea - level.
  • Air pressure increases with decreasing altitude. So air pressure is higher at low altitudes, not lower.
  • As you climb a mountain (increase in altitude), air pressure decreases, not increases.
  • The weight of the air above exerts more force on the air at the bottom of an air - column.
  • As you descend a mountain (decrease in altitude), air pressure increases and air molecules are closer together.

Answer:

  • Air is less dense on a mountaintop than at sea level.
  • More force pushes on the air at the bottom of an air column.
  • As you descend a mountain, air molecules are closer together.
