Ocean Currents

What are stream-like movements of water that flow across the ocean called?

• Wind Currents

• Deep Currents

• Coriolis Effect

• Surface Currents

Where does the Gulf Stream and other warm-water currents originate from?

• Alaska

• Equator

• North and South Poles

• California

Where do cold-water currents originate from?

• Northern Hemisphere

• California

• Tropics

• North and South Poles

What powers the formation of the ocean currents?

• Wind

• Moon

• Sun

• Ohio

How do warm-water currents affect the climate of the coastal areas that they flow?

• Create a colder climate

• Create a warmer climate

• No change to the climate

• Create extremely hot climate

What are the two things that effect the formation of deep currents?

• Salinity and upwelling

• Salinity and wind

• Temperature and wind

• Temperature and Salinity

What is the name of the process in which cold, nutrient dense water from the deep ocean rises to the surface and replaces warm surface water?

• Upwelling

• Coriollis Effect

• Continental Deflection

• Global Winds

The density of the ocean water will increase when it

• joins the gulf stream

• turns to ice

• gets warmer

• gets colder

As water gets dense or the density increases, how does it move?

• expands towards warmer water

• gets pulled up towards the poles

• Sinks towards the ocean floor

• gets pulled up by evaporation

What best describes the gulf stream?

• Powerful warm-water current in the Atlantic Ocean?

• Powerful cold-water current in the Atlantic Ocean?

• Powerful warm-water current in the Pacific Ocean?

• Powerful cold-water current in the Atlantic Ocean?
