Ocean Currents
These are streamlike movements of water that occur at or near the surface of the ocean.
What are surface currents?
This movie portrayed the East Australian Current.
What is the Finding Nemo?
This would happen if the Earth's surface were covered only in water.
What is currents would travel in fixed patterns?
These are stream-like movements of water below the ocean's surface.
What are deep currents?
What are waves?
Surface currents are caused by these.
What are global winds blowing across the Earth's surface?
This current is 100km wide, 1.5km deep, and flows up to 7km/h.
What is the East Australian Current?
This is known as continental deflection.
What is when currents meet landforms and change direction?
Temperature and salinity affect this.
What is the density of ocean water?
This is the highest point on a wave.
What is the crest?
This causes surface currents to move in curved paths as opposed to straight lines.
What is the rotation of the Earth?
This is the amount of water the EAC transports southward each second.
What is 40 million cubic meters?
These begin near the equator and travel to colder parts of the world.
What are warm water currents?
Ocean water is denser when this happens.
What is getting saltier or colder?
This is the lowest point on a wave.
What is a trough?
This stream is one of the longest ocean currents and flows from Florida to Iceland.
What is the Gulf Stream?
The EAC is more like this than a tube.
What is a ribbon?
These begin near the poles and flow to warmer parts of the world.
What are cold water currents?
Deep currents are not controlled by these.
What are winds and the Coriolis effect?
A wavelength is this.
What is the distance between adjacent crests or troughs?
These four things also cause surface currents.
What are global winds, the Coriolis effect, continental deflections, and the water temperature?
These are the dimensions of the EAC.
What is 100km wide & 1.5km deep?
Surface currents can cause these.
Starting at this depth, the water becomes colder as depth increases.
What is 200 meters?
This is why ocean waves form.
What is the friction between the wind and the surface of the water?
