Review Chapter 14
The movement of ocean water is driven by differences in
density and temperature, by wind, and by the moon’s gravity.
Ocean water contains streamlike movements of water called
Horizontal, streamlike movements of water that occur at or near the surface of the ocean are called
one of the longest surface currents—it transports 25 times more water than all the rivers in the world.
Surface currents are controlled by three factors:
global winds, the Coriolis effect, and continental deflections
The apparent curving of moving objects from a straight path due to the Earth’s rotation is called
the Coriolis effect
When surface currents meet continents,
the currents deflect, or change direction
Streamlike movements of ocean water located far below the surface are called
deep currents form in parts of the ocean where water density
is the amount of matter in a given space, or volume.
The density of ocean water is affected by
temperature and salinity—a measure of the amount of dissolved salts or solids in a liquid.
Both decreasing the temperature of ocean water and increasing the water’s salinity increase
Water density depends on
temperature and salinity
is a process in which cold, nutrient-rich water from the deep ocean rises to the surface and replaces warm surface water,
Every 2 to 12 years, the South Pacific trade winds move less warm water to the western Pacific than they usually do
is a periodic change in the eastern Pacific Ocean in which the surface-water temperature becomes unusually cool
A __________ is the highest point of a wave.
A _________ is the lowest point of a wave.
The distance between two adjacent wave crests or wave troughs is a
The vertical distance between the crest and trough of a wave is called the
Deep water waves become shallow water waves when they reach deeps of
less than one half of their wave length.
his movement of water, which carries sand, rock particles, and plankton away from the shore, is called an
When waves hit the shore at an angle, they cause water to move along the shore in a current called a
are white, foaming waves with very steep crests that break in the open ocean before the waves get close to the shore.
are rolling waves that move steadily across the ocean.
are waves that form when a large volume of ocean water is suddenly moved up or down.
A local rise in sea level near the shore that is caused by strong winds from a storm, such as a hurricane, is called a
are caused by the gravitational forces of the moon and sun on the Earth.
The ________ _______ is the main force behind the tides.
The four different types of tides are:
high tides, low tides, spring tides, and neap tides.
