Ocean Currents

Front

What is the Earth's greatest source of energy?

Back

The Sun.

Front

Why is ocean water more dense than fresh water at the same temperature?

Back

Due to differences in salinity.

Front

What is the process called when deep, cold, nutrient-filled water rises to the surface of the ocean?

Back

Upwelling.

Front

How does the density of salt water compare to fresh water?

Back

Salt water is more dense than fresh water.

Front

What impact does plastic waste in the oceans have on marine life?

Back

Animals can get sick after mistaking them for food, or accidentally get caught in the plastic.

Front

What are ocean currents?

Back

Large-scale movements of water within the oceans, driven by factors like wind, salinity, and temperature differences.

Front

What is salinity?

Back

The concentration of salts in water, which affects water density.

Front

What are surface currents?

Back

Ocean currents that occur in the upper layer of the ocean, primarily driven by wind.

Front

What are deep currents?

Back

Ocean currents that flow deep beneath the surface, driven by differences in water density.

Front

What role do ocean currents play in climate?

Back

They help regulate temperatures by distributing heat around the planet.
