Back

A strong equatorial countercurrent develops in the Pacific.

Front

Which ocean surface current carries the greatest volume of water?

Back

The West Wind Drift.

Front

How do countercurrents and undercurrents generally move compared to the surface current above?

Back

They move slower and in the opposite direction.

Front

What is the indirect, ultimate source of most of the energy for ocean currents?

Back

The sun.

Front

What is the primary effect of an El Niño event on global weather patterns?

Back

It can lead to increased rainfall in some regions and droughts in others.

Front

What is the role of the West Wind Drift in ocean circulation?

Back

It helps to distribute heat and regulate climate by moving warm water from the equator towards the poles.

Front

Define countercurrent in the context of ocean currents.

Back

A countercurrent is a current that flows in the opposite direction to the main current.

Front

What is the significance of the sun in ocean currents?

Back

The sun provides the energy that drives the movement of ocean currents through heating and wind patterns.

Front

What type of weather is typically associated with a warm front?

Back
