Ocean Surface Currents (Slides 1 &2
streamlike movements near the surface of a ocean is called..
surface currents
The East Australian Current does flow along
the East coast of
austrailia
If Earth's surface were covered only with , currents would travel in a fixed pattern across the Earth, but Earth’s surface is not covered only with .
water
are stream-like movements of ocean water far below the ocean surface.
deep currents
Waves are made of two main components - and
crests, troughs
surface currents are controlled by four factors
water temperture,global winds,the colioris effect,conential defections.
And it
does flow from the Great Barrier
Reef.
southward
When currents meet landforms, they change .
direction
Deep currents are not controlled by wind or
the coriolis effect
A is the highest point
crest
global winds blowing across the earths surface create
surface currents
Speeds in the core of the EAC are
among the strongest in the South Pacific, up
to 4.5 mph an hour.
4.5 mph
This is known as continental .
deflection
Deep currents are mainly controlled by increases in water .
density
the is the lowest point.
trough
the rotation of the earth causes
surface currents
But actually the real East Australian Current is much than in the movie
bigger and much wilder
Warm water currents begin near the and carry warm water to the other parts of the ocean.
equator
and salinity affect the density of ocean water.
temperture
A is the distance between two adjust crests or troughs
wavelength
Because of the Coriolis Effect, currents in the Northern Hemisphere turn clockwise
Coriolis Effect
just not so conducive to
surfing.
Cold water currents begin closer to the and carry cool water to other parts of the ocean.
poles
Ocean water gets when it becomes saltier or gets colder.
denser
Wave height is the distance between a waves crest and its trough.
