Surface currents
Why do surfaces not move?
Controlled by 4 factors.
How big is the current transport staggering?
40 million cubic meters of water each second.
Warm water currents begin near the equator and carry?
warm water to other parts of the ocean.
Temperature and salinity affect?
the density of ocean water.
A crest is the?
highest point and the trough is the lowest point.
the rotation of the Earth?
causes surface currents to move in curved paths rather than straight lines.
The East Australian Current does flow along?
the East coast of Australia, obviously.
Cold water currents begin closer to the poles and?
carry cool water to other parts of the ocean.
Starting at a depth of about 200 meters, the water temperature becomes?
colder as the depth increases.
Ocean waves form because of?
friction between the wind and the surface of the water.
Stream like movements of water that occur at or near the surface of the ocean are called?
Surface currents.
How fast do the currents flow the in the core of the EAC?
4.5 mph an hour.
When currents meet landforms, what do they do?
they change direction.
Deep currents are mainly controlled by?
increases in water density.
Ocean waves are called mechanical waves because
they travel through a medium.
The Gulf Stream, which is one of the longest surface currents, transports ?
25 times more water than all of the rivers in the world and flows from Florida to Iceland.
The East Australian Current is?
not the fast-flowing warp-tube as it’s portrayed in the movie – it’s an even better ride than that.
Surface currents greatly affect?
Climate in many parts of the world.
The denser water moves along the ocean floor what happens?
eventually travels toward the equator in the form of a deep current.
Mechanical waves are waves that require what?
A medium.
Surface currents can reach depths of?
several hundred meters and lengths of several thousand kilometers.
coastline current is almost?
100 km wide,and more than 1.5 km deep.
Cold water currents begin closer to the poles and carry?
cool water to other parts.
As a result, the volume of the water?
Decreases.
A wave is defined as a?
transfer of energy.
