ocean surface currents
Streamlike movements of water that occur at or near the surface of the ocean are called
surface currents
Speeds in the core of the EAC are among the strongest in the
South Pacific
If Earth's surface were covered only with water, currents would travel in a fixed pattern across the
earth
Deep currents are stream-like movements of ocean water far below the ocean
surface
what are the two componets waves are made out of
crest and troughts
global winds blowing across the earth's surface creates?
surface currents
the east Australin current is much bigger in the movie or smaller?
bigger
when currents meet landforms what do they do?
they well change direction.
deep currents are mainly controlled by?
increases in water density.
what is a wavelength?
A wavelength is the distance between two adjust crests or troughs.
the rotation of the Earth causes surface currents to move in?
curved paths!
The East Australian Current does flow along the East coast of
Australian
can currents carry warm water
yes!
ocean water gets denser when it becomes
sailter or colder.
why do ocen waves form
because of friction between the wind and the surface water.
currents in the Northern Hemisphere turn clockwise while currents in the Southern Hemisphere turn
counterclockwise!
the east australian current transports a staggering 40million cubic meters of water each
secound
do water currents affect the climate?
yes
starting at a depth of about 200 meters, the water temature becomes
colder as depth increases.
what does the noise of the wave do to our eardroms
vibrates them.
Surface currents are controlled by four factors
global winds, the Coriolis effect, continental deflections, and the water temperature.
the current infact is more like a ribbon then a
tube
surface currents don't affect the atmophere. is this right or wrong?
wrong
the ocean floor eventally travels to the
equator
what are mechanical waves?
Mechanical waves are waves that require a medium. This means that they have to have some sort of matter to travel through. These waves travel when molecules in the medium collide with each other passing on energy.
