Ocean Currents
What type of currents are also called surface currents?
Wind driven currents
A is a narrow,
powerful surface current?
Rip current
The is the
movement of wind and water to the
right or left, that is caused by
Earth’s rotation.
Coriolis Effect
Upwelling brings cold, nutrient-rich water from in the ocean to the ocean’s surface.
deep
Density currents circulates
Nutrients and gasses
Earth’s major wind belts, called , influence the formation of ocean currents and the direction they move.?
Prevailing winds
A rip current is a narrow,
powerful surface current which
flows from the shore?
Away
The Corilis effect is caused by what?
The earth rotation
Deeper water then rises to replace it.
Colder
Density currents circulate energy
Thermal energy
extend to about 400 m below the
surface, and they move as
fast as 100 km/day.?
Surface currents
A rip current is caused by building up?
Pressure.
The Coriolis effect also causes fluids to curve to the
left in the hemisphere
Southern
Upwelling occurs when wind blows across the .
The Oceans surface
Density Currents are
caused by changes
in
Density
An is a
large volume of water
flowing in a certain
direction?
Ocean current
They can flow very and can be difficult to detect until you are in one.
quickly
It causes fluids such as to curve to the right in the Northern hemisphere, in a clockwise direction.
Air and water
Upwelling is the vertical movement of water toward the .
Oceans surface
Density Currents are a type of that
carries water from the surface to deeper parts of the
ocean.
Vertical currents
What types of currents carry warm or cold water horizontally across the ocean’s surface?
Surface currents
It is caused by pressure
building up from
Build-up of water from waves?
uneven
It causes fluids such as air and water to curve to the right in the hemisphere, in a clockwise direction.
Nothern hemisphere
Upwelling often occurs along .

Density Currents are caused by changes in density rather than .
