ocean surface currents
Streamlike movements of water that occur at or near the surface of the ocean are called
Surface Currents.
The East Australian Current transports staggering
40 million cubic metres of water
If Earth's surface were covered only with water, currents would travel in a fixed pattern
across the Earth,
temperature and salinity affect the density of
ocean water
Waves are made of two main components -
crests and troughs
Surface currents are controlled by four factors: global winds,
the Coriolis effect, continental deflections, and the water temperature.
The eastern australian current is almost
100km
When currents meet land forms, they change direction. This is known as
continental deflection.
Ocean water gets denser when it becomes saltier or
colder
A crest is the highest point and the trough is the
lowest point.
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
Speeds in the core of the EAC are among the strongest in the South Pacific, up
4-5 mph
Warm water currents begin near the
equator
The denser water moves along the ocean floor and eventually travels toward the
equator
Ocean aves form because of
friction
Surface currents can reach depths of several hundred meters and lengths
several thousand kilometers.
What is the easy nickname for the eastern australian current--
The EAC
Surface currents greatly affect the
Climate
water becomes denser. Starting at a depth of about
200 Meters
Waves move in What kind of a pattern
circular patterns
Global winds blowing across the Earth’s surface create
surface currents.
How deep is the EAC
1.5 kilometer
Cold-water currents create cooler climates in coastal areas that would
Warmer
the water temperature becomes colder as
The depth decrease
A wave is defined as a
Energy transfer
