Wind and Ocean Circulation Review

What is an ocean current?

• the movement of water in regular patterns below the surface of the ocean

• the stream-like movement of ocean water in a regular pattern

• a horizontal movement of water in a regular pattern at the ocean’s surface

• the sinking of dense water and the rising of less dense water in a circular path

What is a surface current?

• the stream-like movement of ocean water in a regular pattern

• the movement of matter due to differences in density

• the energy transfers from the wind to the ocean

• the horizontal movement of water in a regular pattern at the ocean’s surface

How are ocean currents created?

• by the energy transfer from the wind to the ocean

• by global winds, the locations of the continents, and Earth’s rotation

• by global circulation patterns

• by movement of matter due to differences in density

What are gyres?

• the temperature and salinity of the water

• Earth’s deep ocean currents flowing in huge circular patterns

• the movement of water in regular patterns below the surface of the ocean

• Earth’s surface currents flowing in huge circular patterns

What factors affect the density of ocean water?

• carbon

• gravity

• the salinity of the water

• the temperature of the water

What are deep ocean currents?

• the stream-like movement of ocean water in an irregular pattern

• the movement of water in regular patterns below the surface of the ocean

• the stream-like movement of ocean water in a regular pattern

• the movement of water in regular patterns above the surface of the ocean

What affects deep ocean currents?

• Earth’s rotation

• density differences in ocean water

• global winds

• the locations of the continents

What is convection?

• the energy transfers from the wind to the ocean

• the movement of matter due to similarities in density

• the sinking of dense water and the rising of less dense water in a circular path

• the movement of matter due to differences in density

What matter is cycled in the ocean?

• oxygen and carbon dioxide

• Pollution

• dissolved solids and gases

• marine organisms

• ocean water itself

Waves are formed when

• Wind scrap across the ocean

• Water level increases

• Water level decreases
