Surface currents are primarily caused by
the movement of water
the wind
warm water
the equator
The curved paths of global winds and surface currents are caused by
the rotation of the earth
the revolution of the earth around the Sun
Deep ocean currents
warm air near the equator
Ocean currents in the Northern and Southern Hemispheres turn
from west to east
clockwise
in opposite directions
against the Earth's rotation
The density of ocean water increases when it
joins the Gulf Stream
turns to ice
gets warmer
gets colder
Which process increases the salinity of ocean water?
convection currents
condensation
Coriolis effect
evaporation
What causes a giant wave, known as a tsunami, to occur?
The weather turns hotter or colder.
Convection currents below the surface.
Water gets sucked below the surface.
A LARGE volume of ocean water moves up and down, such as from an earthquake.
Trying to roll a ball straight across a turning merry-go-round is a demonstration of what happens in the
Coriolis effect.
flow of currents and countercurrents at the equator.
movement of global winds across the surface of the ocean
deflection of a current against a continent.
Compared with surface currents, deep currents are
colder and denser
warmer and less dense
warmer and denser
colder and less denser
How do warm-water currents affect the coastal areas along which they flow?
They create greater rainfall along the coast.
They create unusually cool climates for the latitude.
They make the coastal climate cooler than the inland climate
They create unusually warm climates for the latitude.
An earthquake causes a tsunami because force from the quake
pulls water down toward the source of the quake.
pushes a large body of water up from the ocean floor.
blows surface water away from the shore.
meets the force of currents flowing in a different direction.
What happens to an ocean current when it hits a continent?
It moves toward the poles.
It changes direction.
It moves toward the equator.
It speeds up.
What happens to the water that is left behind after evaporation?
It gets hotter.
It gets less dense.
Its salinity increases.
It moves faster to stay warm.
