Chapter 14 Currents, Waves, & Tides

Which phrase describes a surface current?

• get cool near the equator
• flows like a stream
• stretches from north to south
• creates global winds

In what direction do global winds and currents flow near the equator

• east to west
• west to east

How does the Coriolis effect make ocean currents appear to move?

• back and forth
• in a curved path
• clockwise
• against  the Earth's rotation

What happens to an ocean current when it hits a continent?

• it changes direction
• it moves toward the poles
• it moves toward the equator
• it speeds up

How are deep currents different form surface currents?

• warmer and faster
• caused by wind
• denser and slower
• some are colder than others

What happens to water when the air above it gets cold?

• evaporates
• get denser
• moves faster to stay warm
• salinity increases

Whats to the water that is left behind during evaporation?

• gets hotter
• gets less dense
• moves faster to stay warm
• salinity increases
