Back

Wind is caused by the uneven heating of Earth's surface, which creates differences in air pressure.

Front

What is a cumulonimbus cloud?

Back

Cumulonimbus clouds are tall, dense clouds associated with thunderstorms and can produce hail.

Front

What is El Niño?

Back

El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean, affecting weather patterns.

Front

What is the subtropical jet stream?

Back

The subtropical jet stream is a fast-flowing air current in the atmosphere that influences weather patterns, especially in winter.

Front

How does unequal heating of the land affect weather?

Back

Unequal heating causes air to move from high-pressure areas to low-pressure areas, creating wind.

Front

What type of weather is associated with a cold front?

Back

Cold fronts typically bring cooler temperatures and can lead to thunderstorms.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, like wind, caused by Earth's rotation.

What type of weather is indicated by a weather map showing low pressure?

Back

Low pressure often indicates stormy weather, including rain or snow.

Front

What is a weather front?

Back

A weather front is a boundary between two different air masses, which can lead to changes in weather.

Front

What is the role of the sun in weather patterns?

Back

The sun provides energy that heats the Earth's surface, driving weather patterns and systems.
