What is a cold front?

Back

A cold front is a boundary between a mass of cold air and a mass of warm air, where the cold air pushes under the warm air, often leading to precipitation and thunderstorms.

Front

What happens when a cold front approaches?

Back

It usually produces intense thunderstorms due to the lifting of warm, moist air over the cold air.

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, which can lead to warmer temperatures and increased rainfall in some regions.

Front

What are some effects of El Niño?

Back

Warmer temperatures and more rain in certain areas, affecting weather patterns globally.

Front

What is the Gulf Stream?

Back

The Gulf Stream is a warm ocean current that originates in the Gulf of Mexico, flows along the U.S. East Coast, and warms the UK.

Front

How does the Gulf Stream affect climate?

Back

It helps to moderate the climate of the regions it flows past, making them warmer than they would be otherwise.

Front

What causes wind?

Back

Wind is produced by differences in air temperatures, which create pressure differences in the atmosphere.

Front

What is a sea breeze?

Back

A sea breeze is a local wind that occurs when the land heats up faster than the ocean, causing cooler air from the ocean to move inland.

Front

Why do sea breezes occur?

Back

They occur because the land warms up more quickly than the ocean, creating a temperature difference that causes air to move from the ocean to the land.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.
