Energy in the Atmosphere and Oceans

Front

What is the transfer of heat by direct contact?

Back

Conduction

Front

What happens to hot air and cold air in terms of density?

Back

Hot air is less dense so it rises, and cold air is more dense so it sinks.

Front

What do ocean currents bring from the equator towards Earth's poles?

Back

Warm water.

Front

What happens to ocean water as salt water forms into ice?

Back

The ocean water becomes more salty.

Front

Where does convection occur on Earth?

Back

In oceans, mantle (magma), and atmosphere.

Front

What is the process called when heat is transferred through fluids (liquids and gases)?

Back

Convection.

Front

What is the primary source of energy for Earth's atmosphere and oceans?

Back

The Sun.

Front

What is the term for the movement of water in the ocean caused by wind and differences in temperature and salinity?

Back

Ocean currents.

Front

What is the effect of temperature on the density of air?

Back

Hot air is less dense and rises; cold air is more dense and sinks.

Front

What is the term for the energy transfer through electromagnetic waves?

Back

Radiation.
