Ocean currents

Front

What are the two main factors that affect the density of deep ocean water?

Back

Temperature and salinity.

Front

What does upwelling bring to the ocean surface?

Back

Nutrients.

Front

Which side of a mountain is typically dry?

Back

Leeward side.

Front

What natural events can cause tsunamis?

Back

Underwater disturbances such as earthquakes, landslides, and volcanoes.

Front

What influences surface ocean currents?

Back

Wind, Coriolis effect, and continental deflection.

Front

What is the Coriolis effect?

Back

The deflection of moving objects caused by the rotation of the Earth.

Front

How does temperature affect ocean water density?

Back

Colder water is denser than warmer water.

Front

What role does salinity play in ocean water density?

Back

Higher salinity increases the density of ocean water.

Front

What is upwelling?

Back

The process where deep, cold, nutrient-rich water rises to the surface.

Front

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

Back

Surface currents are driven by wind, while deep ocean currents are influenced by density differences.
