Solution

The correct choice is A

Altitude increases, force per unit area decreases

Atmospheric pressure: It can be defined equally the full weight of air over a unit of measurement area at whatsoever given peak.

As the height increment, the amount of air over a unit area decreases. Hence, the atmospheric pressure will reduce as well.

Explanation for the correct options:

Option A:

1. As distance increases, the amount of air over a unit area decreases.
2. Therefore, the atmospheric pressure level will reduce due to lower air molecules.
3. Hence, this is the right option.

Caption for the incorrect options:

Choice B:

1. As altitude decreases, the amount of air over a unit area increases.
2. Therefore, the atmospheric force per unit area will increment due to the high amount of air molecules.
3. Hence, this is not the correct option.

Pick C:

1. As distance increases, the amount of air over a unit area decreases.
2. Therefore, the atmospheric pressure will reduce due to lower air molecules.
3. Hence, this is non the right option.

Option D:

1. According to the definition of atmospheric force per unit area, it is articulate that it depends on the distance.
2. Hence, this is non the correct option.

Hence, selection A is the right pick.
