Currents that Impact Europe

____________ is the process by which heat is transferred by movement of air or water.

• Convection

• Conduction

• Radiation

• Coriolis effect

Which of the following statements describes the relationship between density and temperature? 

• Cold water is denser than warm water
• Warm water is denser than cold water
• Warm and cold water equal densities
• The density of water is not affected by temperature

What two factors determine the density of water in deep currents? 

• Salinity and temperature
• Coriolis Effect and wind
• Upwelling and dissolved solids
• Continental deflection and convection

What 3 factors most directly affect surface currents in the ocean? 

• Dissolved solids, gases & energy
• Upwelling, convection & sun's energy
• Deep currents, convection currents & surface wind
• Surface wind, Coriolis effect & continental deflection

Deep ocean currents are caused by differences in density of the water.  Which statement accurately describes the relationships between salinity, temperature, and density of ocean water? 

• Cold water, holding less salt, sinks towards the bottom of the ocean. 
• Warm water, holding more salt, sinks towards the bottom of the ocean. 
• Warm water, holding less salt, rises toward the surface of the ocean. 
• Warm water, holding more salt, rises towards the surface of the ocean. 

Warm ocean currents generally come from

• the North Pole.
• the South Pole.
• the Equator.
• both the North and South pole.

Cold ocean currents generally come from

• the North Pole .
• the South Pole.
• the Equator.
• both the North and South pole.

The Gulf stream carries _____________ water from the east coast of The United States to the West coast of Europe.

• Cold
• Warm 
• Freezing
• Fresh

How do warm-water currents affect the coastal areas along which they flow?

• Cool the coast

• Warm the coast

• Cause snow to fall

• Cause higher tides

Why would places near the north with the same latitude have very different climates?

• One place is near a warm ocean current.

• It is not possible.

• They get more sunlight than the other location.
