Answer:
Atmospheric pressure
Step-by-step explanation:
In simple words, The pressure within Earth's atmosphere is known as atmospheric pressure, or barometric pressure (after the barometer). The normal atmosphere is a pressure unit specified as 101,325 Pa, which is equal to 760 millimetres of mercury, 29.9212 inches of mercury, or 14.696 pounds of tension. The atm unit approximately corresponds to Earth's average sea air pressure.
Thus, we can conclude that the correct answer is atmospheric pressure.
