Front

What type of pressure system usually brings light winds, fair weather, and sunny skies?

Back

High pressure.

Front

What type of pressure system causes clouds and precipitation?

Back

Low pressure.

Front

What type of pressure system is associated with clear, sunny skies?

Back

High pressure.

Front

What happens to air that cools?

Back

It becomes more dense and sinks.

Front

What is it called when a fast-moving cold air mass pushes a warm air mass up?

Back

A cold front.

Front

What is the definition of convection currents?

Back

The movement of air caused by the uneven heating of the Earth's surface, leading to rising warm air and sinking cool air.

Front

What weather phenomenon is typically associated with low pressure systems?

Back

Storms and precipitation.

Front

What is the role of high pressure systems in weather?

Back

They generally lead to stable, clear weather conditions.

Front

How does temperature affect air density?

Back

Warm air is less dense and rises, while cool air is more dense and sinks.

Front

What is a warm front?

Back

A boundary where a warm air mass rises over a cold air mass, often leading to gradual precipitation.
