Question

How does altitude affect air pressure and density? Check all that apply.

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

Answer 1

the correct options are:
- Air is less dense on a mountaintop than at sea level.
- As you climb a mountain, air pressure decreases.
- More force pushes on the air at the bottom of an air column.
