What is a Sea Breeze?

Back

A Sea Breeze is a cool breeze that blows from the sea to the land during the day, caused by the temperature difference between the land and the sea.

Front

What type of pressure is created when warm air rises?

Back

Low Pressure.

Front

How does the density of warm air compare to cold air?

Back

Warm air is less dense than cold air.

Front

What is the primary source of energy that creates winds?

Back

The Sun.

Front

What is Conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is Convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is Radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Front

What causes a Land Breeze?

Back

A Land Breeze occurs at night when the land cools faster than the sea, causing cooler air to flow from the land to the sea.

Front

What is the role of the Sun in convection currents?

Back

The Sun heats the Earth's surface, causing warm air to rise and create convection currents.

Front

What happens to air pressure when warm air rises?

Back

Air pressure decreases in the area where warm air rises.
