Currents (Slides 1 & 2)
Streamlike movements of water that occur at or near the surface of the ocean are called ______
Surface Currents
The East Australian Current flows along the ____ coast of Australia.
East
When currents meet landforms, they change direction. This is known as ______________.
Continental Deflection
____________ are stream-like movements of ocean water far below the ocean surface.
Deep Currents
Waves are made of two main components - ______ and _______.
Crests, Troughs
25
The East Australian Current flows __________ from the Great Barrier Reef.
Southward
Warm water currents begin near the _________ and carry warm water to other parts of the ocean.
Equator
Deep currents are mainly controlled by increases in ___________.
Water Density
A __________ is the distance between two adjust crests or troughs.
Wavelength
The four factors that control Surface Currents are global winds, the Coriolis effect, continental deflections, and the _____ temperature.
Water
Speeds in the core of the East Australian Current can go up to ___ mph.
4.5
Cold water currents begin closer to the _____ and carry cool water to other parts of the ocean.
Poles
Starting at a depth of about ___ meters, the water temperature becomes colder as the depth increases.
200
___________ is the vertical distance between a waves crest and its trough.
Wave Height
_____ winds blowing across the Earth’s surface create surface currents.
Global
The East Australian Current transports __ million cubic meters of water southward every second.
40
Warm-water currents create warmer climates in coastal areas that would otherwise be much cooler, example: _______
Iceland
Temperature and ________ (the saltiness or amount of salt dissolved in a body of water) affect the density of ocean water.
Salinity
Ocean waves form because of ________ between the wind and the surface of the water.
Friction
Because of the ______ Effect, currents in the Northern Hemisphere turn clockwise while currents in the Southern Hemisphere turn counterclockwise.
Coriolis
The East Australian Current is almost ___ km wide and over ___ km deep.
100, 1.5
Cold-water currents create cooler climates in coastal areas that would be much warmer, example: ____________
San Francisco
______ water moves along the ocean floor and eventually travels toward the equator in the form of a deep current. Less-_____ water always flows on top of ______ water.
Denser, Dense, Denser
__________ waves are waves that require a medium (they have to have some sort of matter to travel through).
