The density of ocean water increases when it
a) joins the Gulf Stream
b) turns to ice
c) gets colder
d) gets warmer
Why are surface currents warmer than deep currents?

b) Underwater volcanoes heat the surface of the water
c) The water is absorbing the lands heat all the time making it warmer
d) The boats in the ocean heat up the surface
Which currents carry warm water away from the equator?
a) freezing
b) surface currents
c) deep currents
d) evaporation
How do warm-water currents affect the coastal areas along which they flow?
a) They create greater rainfall along the coast.
b) They make the coastal climate cooler than the inland climate.
c) They create unusually warm climates for the latitude.
d) They create unusually cool climates for the latitude.
As water gets denser, how does it move?
a) gets pushed toward the poles
b) expands toward warmer water
c) sinks toward the ocean floor
d) gets pulled up by evaporation
Surface currents are caused by
a) the wind
b) the equator
c) warm water
d) floods
Compared with surface currents, deep currents are
a) warmer and less dense
b) colder and less dense
c) warmer and denser
d) colder and denser
When the air above water gets cold, what happens to water molecules?
a) The molecules slow down and move closer together, increasing the water’s density.
b) The denser water floats on top of the chilled water.
c) The water’s volume increases as molecules move closer together.
d) The water molecules evaporate, decreasing the water’s density.
