Ocean water contains streamlike movements of
water called ocean currents. Currents are influenced by a number of factors, including weather, the Earth's rotation,
and the position of the continents.

There are twotypes of ocean
currents:

Surface Currents:Horizontal, streamlike
movements of water that occur at or near the
surface of the ocean are called surface currents

Surface Currents:The Gulf Stream is one of
the longest surface currents.

Surface Currents:Surface currents are controlled by three
factors which keep surface currents flowing in
distinct patterns around the Earth.

Surface Currents:1. Global Winds - winds
that blow across the Earth's surface to create surface currents in the
ocean.

Surface Currents:Different winds cause
currents to flow in differentdirections. Near the equator, the winds blow ocean water
east to west, but closer to the poles, ocean water is blown
west to east.

Surface Currents:2. Coriolis Effect - The Earth's rotation causes
wind and surface currents to move in curved paths rather than in straight
lines.

Surface Currents:The Coriolis Effect causes
surface currents in the Northern Hemisphere to turn clockwise, and surface currents in the Southern Hemisphere
to turn counterclockwise.

Surface Currents:3. Continental deflections -When surface currents meet
continents, the currents deflect, or change direction.

Surface Currents and Climate
Surface currents greatly affect the climate in many parts of
the world. Some surface currents warm or cool coastal
areas year-round.

Surface Currents and Climate
Surface currents are affected by the
temperature of the water in which they form.

Surface Currents and Climate
Surface currents are classified as warm-water
or cold-water.

Surface Currents and Climate
1. Warm-water currents begin near the equator
and carry warm water to other parts of the ocean.

2. Cold-water currents begin closer to the poles and carry cool water to
other parts of the ocean.

Deep Currents:Streamlike movements of
ocean water located far below the surface are called
deep currents.

Deep Currents:Deep currents are notdirectly controlled by
wind.Deep currents form in
parts of the ocean where water density increases.

Deep Currents:The density of ocean water is affected by
temperature and salinitySalinity is how much salt is
dissolved in the water.

Deep Currents:Decreasing the temperature
of ocean water and increasing the water's
salinity increase the water's density.
