Surface Currents
Currents flow like rivers in patterns around the Earth.
What are Surface currents?
Are stream-like movements of ocean water far below the ocean surface.
What are Deep currents?
The East Australian Current does flow along
the East coast of Australia,
What is the East Australian Current?
Waves are made up of two main components.
What are the following?
1 Crests.
2 Trough.
Are waves that require a medium.
What is a Mechanical wave?
Global winds blowing across The Earth.
What create Surface currents?
The diagram at the right shows how deep currents and surface currents interact and trade places.
How dose that diagram show surface currents.
And it does flow southward from the Great Barrier
Reef.
What is the Great Barrier Reef?
Is the distance between two adjust crests or troughs.
What is Wavelength?
It's the energy that travels with the wave.
What is the energy that travels in a wave?
Just as with winds, the rotation of the Earth causes surface currents to move in curved paths rather than straight lines.Because of the Coriolis Effect,
What dose the Coriolis effect do to surface currents?
Deep currents are mainly controlled by increases in water density.
What is water density?
The current is almost 100 km wide, and more than 1.5 km deep
What is the EAC more like?
Ribbon or Tube?
Is the vertical distance between a waves crest and its trough.
What is Wave height?
One example of a mechanical wave is.
What is sound?
Surface currents greatly affect the climate in many parts of the world.
What is Climate?
Ocean water gets denser.
What makes Ocean water denser?
Speeds in the core of the EAC are
among the strongest in the South Pacific
What are the speeds in the EAC?
Waves move is a BLANK pattern.
What is a circular pattern?
This means that they have to have some sort of matter to travel through.
What is a medium?
What are the 4 factors that control surface current?
What are the following...
1 Global winds
2 Coriolis effect
3 Continental deflections
4 Water temperature
Starting at a depth of about 200 meters, the water temperature becomes colder as the depth increases.
What creates Deep Currents?
The East Australian Current transports a staggering BLANK
What is the number of cubic meters.
Form because of friction between the wind and the surface of the water.
What is a Ocean ave?
Other examples include water waves, seismic waves, and waves traveling through a spring.
What are other examples of mediums?
