Ocean currents

Front

What is a sea breeze?

Back

A sea breeze is a cool wind that blows from the ocean to the land, occurring when warm air rises over the land, allowing cooler air from the ocean to move in.

Front

What affects the density of ocean water?

Back

The amount of salt in the water affects its density.

Front

What is El Niño?

Back

El Niño is a climate pattern characterized by warmer ocean temperatures in the Pacific Ocean, which can lead to increased storm activity.

Front

How does warm air compare to cold air in terms of density?

Back

Warm air is less dense than cold air.

Front

What heats up and cools down quicker, land or water?

Back

Land heats up and cools down quicker than water.

Front

What is a land breeze?

Back

A land breeze is a cool wind that blows from the land to the ocean, occurring when warm air rises over the ocean, allowing cooler air from the land to move in.

Front

What is the role of ocean currents?

Back

Ocean currents help regulate the Earth's climate by distributing heat around the planet.

Front

What is the difference between surface currents and deep ocean currents?

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by differences in water density and temperature.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, like ocean currents, caused by the rotation of the Earth.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold water rises to the surface, bringing nutrients that support marine life.
