Weather systems

Front

What is the atmosphere?

Back

A layer of gas and suspended solids extending from the Earth's surface up many thousands of miles, becoming thinner with distance.

Front

What is a land breeze?

Back

A land breeze is a cool breeze that blows from the land towards the sea, typically occurring at night.

Front

What is a sea breeze?

Back

A sea breeze is a cool breeze that blows from the sea towards the land, usually occurring during the day.

Front

What causes a land breeze?

Back

A land breeze is caused by the warm land surface cooling down at night, causing the air above it to become denser and sink.

Front

What time of day do sea breezes typically occur?

Back

Sea breezes typically occur during the day when the land heats up faster than the sea.

Front

What is convection in weather systems?

Back

Convection is the process by which warm air rises and cool air sinks, creating wind and weather patterns.

Front

What is the role of the sun in weather systems?

Back

The sun heats the Earth's surface, causing temperature differences that drive wind and weather patterns.

Front

What happens to air pressure during a land breeze?

Back

During a land breeze, air pressure over the land increases as the air cools, while pressure over the sea decreases.

Front

What is humidity?

Back

Humidity is the amount of water vapor present in the air, which can affect weather conditions.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, and precipitation.
