Surface Currents
Surface currents flow like these around the Earth's oceans.
What are rivers?
This flows southward from the Great Barrier Reef.
What is the East Australian coast?
A fixed pattern.
If Earth's surface were covered only with water, currents would travel in what kind of pattern?
Stream-like movements of ocean water far below the ocean surface.
What are deep currents?
This is the distance between two adjust crests or troughs.
What is a wavelength?
Streamlike movements of water that occur at or near the surface of the ocean.
What are surface currents?
These speeds are reached by EAC in the South Pacific.
What is 4.5 mph?
Currents change direction.
What happens when currents meet landforms?
Deep currents are mainly controlled by this.
What are increases in water density?
This is the highest point of a wave.
What is a crest?
Surface currents are controlled by these 4 factors.
What are global winds, the Coriolis effect, continental deflections, and the water temperature?
This amount of water is moved by the EAC each second.
What is 40 million cubic meters?
This is when currents change direction.
What is continental deflection?
These 2 things affect water density.
What is temperature and salinity?
This is the lowest point of a wave.
What is a trough?
One of the longest surface currents.
What is The Gulf Stream?
This many Olympic swimming pools is equivalent to 40 million cubic meters of water.
What is 16,000?
Warm water currents begin.
What is the equator?
This temperature of water sinks to the ocean floor.
What is cold water?
This is the vertical distance between a wave's crest and its trough.
What is wave height?
These create surface currents by blowing across the Earth's surface.
What are global winds?
The current is almost 100 km wide, and more than 1.5 km deep.
How deep and wide is the current?
These colors designate temperatures to surface currents
What is red and blue?
At this depth, water becomes cooler.
What is 200 meters?
These form because of friction between the wind and the surface of the water.
What are ocean waves?
