What are surface currents?

Back

Surface currents are movements of water that occur at the surface of the ocean, primarily driven by global wind patterns.

What causes the Coriolis Effect?

Back

The Coriolis Effect is caused by the Earth rotating on its axis, which affects the direction of winds and currents.

What are deep currents?

Back

Deep currents are regular movements of water that occur far below the ocean's surface, often driven by differences in temperature and salinity.

What is a gyre?

Back

A gyre is a circular system of currents in the Earth's major oceans, influenced by wind patterns and the Coriolis Effect.

Why are surface currents warmer?

Back

Surface currents are warmer because they are influenced by warmer temperatures and less salinity compared to deeper waters.

What is upwelling?

Back

Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, often supporting marine life.
