HMH- Circulation of Earth's Oceans

Front

Why does cold water sink in a convection current?

Back

Cold water is more dense than warm water, causing it to sink.

Front

What is the circulation of hot and cold fluids (liquids and gases) called?

Back

Convection.

Front

What are regular movements of water far below the ocean's surface called?

Back

Deep Currents.

Front

What two factors affect the ocean's density and cause the Global Conveyor Belt to travel?

Back

Temperature and salinity.

Front

Where do ocean currents bring warm water from the equator?

Back

To the Poles.

Front

What is density?

Back

Density is the mass of a substance divided by its volume.

Front

What is salinity?

Back

Salinity is the measure of the amount of salt in water.

Front

What is the Global Conveyor Belt?

Back

The Global Conveyor Belt is a system of ocean currents that circulate water around the globe.

Front

What role does temperature play in ocean currents?

Back

Temperature affects the density of water, influencing how it moves.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects caused by the rotation of the Earth.
