Front

What happens to warm air in convection?

Back

Warm air rises.

Front

What creates an area of lower pressure in convection?

Back

As warm air rises, it creates an area of lower pressure.

Front

What happens to cooler air when warm air rises?

Back

Cooler air flows in to replace the rising warm air.

Front

What causes winds based on temperature and air pressure?

Back

Winds flow from areas of high pressure to areas of low pressure.

Front

What is the relationship between temperature and air pressure?

Back

As temperature increases, air pressure decreases.

Front

Why does a strong breeze come from the ocean in the afternoon?
