Air Pressure and Wind

Front

What is air pressure?

Back

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

Front

What factors can influence wind speed?

Back

Wind speed can be influenced by temperature differences, pressure gradients, and the Earth's rotation.

What is the Coriolis effect?

Back

The Coriolis effect is the apparent deflection of moving objects (like wind) caused by the rotation of the Earth.

What is a convection cell?

Back

A convection cell is a circular pattern of air movement where warm air rises and cool air sinks, creating a cycle.

What causes sea breezes?

Back

Sea breezes are caused by the differential heating of land and water, leading to pressure differences.

Front

When do sea breezes typically occur?

Back

Sea breezes generally occur during the daytime when the land heats up faster than the sea.

Front

What is the relationship between temperature and air pressure?

Back

As temperature increases, air pressure typically decreases because warm air is less dense.

Front

How does land heat compared to water?

Back

Land heats up and cools down faster than water due to its lower specific heat capacity.

Front

What is the role of temperature differences in wind formation?

Back

Temperature differences create pressure gradients, which drive the movement of air and generate wind.

What happens to air pressure as altitude increases?

Back

Air pressure decreases as altitude increases because there are fewer air molecules above a given point.
