What is air pressure?

Back

Air pressure is the force exerted by the weight of air molecules above a surface. It decreases with altitude.

Why is it hard to breathe at high altitudes?

Back

At high altitudes, there is a low density of air molecules, resulting in lower air pressure and less oxygen available.

Front

What happens to warm air compared to cold air?

Back

Warm air rises, while cold air sinks.

How does air density relate to air pressure?

Back

If the density of air is high, the air pressure is also high.

Front

Where is altitude greater?

Back

Altitude is greater at the top of the mountain.

Front

What is the relationship between altitude and air pressure?

Back

As altitude increases, air pressure decreases.

Front

What is the main component of air?

Back

The main component of air is nitrogen, which makes up about 78% of the atmosphere.

Front

What is the effect of temperature on air pressure?

Back

As temperature increases, air pressure generally decreases because warm air expands.

Front

What is the role of air pressure in weather patterns?

Back

Air pressure differences drive wind and influence weather patterns.
