Answer 2

Atmospheric pressure decreases as a person rises in altitude.

Step-by-step explanation:

• The pressure is the ratio of the weight of the air to unit area. So, as the height increases, the pressure decreases.

• That is, the pressure is inversely proportional to the altitude. At such higher levels, the air molecules are very less than at lower levels.

• Humans can survive up to 20,000 feet that are 3.8 miles above sea level.

• This is due to the decrease in the oxygen rate called hypoxia, which means oxygen deprivation.
