Question

write any two factors on which atmospheric pressure depends​

Answer 1

The 3 main factors that affect barometric (air) pressure are:

• Temperature.
• Altitude or
• Elevation.

Answer 2

Atmospheric pressure varies from place to place and from time to time. This variation depends on the following factors:

• Altitude: At sea level, the air layers are dense, so it exerts greater pressure. Hence, the pressure is higher at sea level and it decreases with the altitude because the air becomes thinner and exerts lesser pressure. The loss of pressure is one centimetre for every ascent of 110 metres.

• Temperature: The temperature also affects the pressure. The hot air expands and is lighter. Hence, it exerts less pressure. On the other hand, cold air contracts and is heavier so exerts high pressure.
