What is the jet stream?

Back

A fast-flowing air current in the atmosphere that influences weather patterns.

Front

In which layer of the atmosphere do we experience weather?

Back

Troposphere.

Front

What causes wind?

Back

Wind is caused mainly by air pressure differences that result from uneven heating of the Earth's atmosphere.

Front

What is the role of the Troposphere?

Back

It is the lowest layer of the atmosphere where all weather events occur.

Front

How does the uneven heating of the Earth affect weather?

Back

It creates air pressure differences that lead to wind and weather changes.

Front

What happens to cool air in relation to the jet stream?

Back

Cool air typically stays south of the jet stream.

Front

What is a high-pressure system associated with?

Back

Front

What is the significance of the Stratosphere?

Back
