Ocean currents and Climate 18-19

Front

What causes a land breeze?

Back

A land breeze is caused by temperature differences between the land and the sea, typically occurring at night when the land cools faster than the sea.

Front

What happens to water as it gets denser?

Back

As water gets denser, it sinks toward the ocean floor.

Front

When is a sea breeze most likely to occur?

Back

A sea breeze is most likely to occur during the day when the land heats faster than the surface of the sea.

Front

What weather conditions are associated with frequent rainfall?

Back

Frequent rainfall is often associated with warm, moist air rising and cooling, leading to condensation and precipitation.

Front

Which current is known as a cold water current?

Back

The Humboldt Current is known as a cold water current.

Front

What is the definition of ocean currents?

Back

Ocean currents are large-scale movements of water within the world's oceans, driven by factors such as wind, temperature, salinity differences, and the Earth's rotation.

Front

How do ocean currents affect climate?

Back

Ocean currents help regulate climate by distributing heat around the planet, influencing weather patterns and temperatures in coastal regions.

Front

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

Back

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

Front

What role does the Coriolis effect play in ocean currents?

Back

The Coriolis effect causes moving water to turn and twist, influencing the direction of ocean currents based on the Earth's rotation.

Front

What is upwelling?

Back

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