Ocean Surface
Streamlike movements of water that occur at or near the surface of the ocean are called
Surface Currents
How long are the Speeds In the Core?
Speeds in the core of the EAC are
among the strongest in the South Pacific, up
to 4.5 mph an hour.
What is Water Temperature?
Warm water currents begin near the equator and carry warm water to other parts of the ocean. Cold water currents begin closer to the poles and carry cool water to other parts of the ocean. The map below shows the Earth's surface currents.Warm water currents are shown in red, and cold water
True or False? Some surface currents Cold and some cool coastal areas year-round. This causes changes in the atmosphere that disrupt the climate in many parts of the world.
False
True: Some surface currents warm and some cool coastal areas year-round. This causes changes in the atmosphere that disrupt the climate in many parts of the world.
Why are Ocean waves are called mechanical waves?
because they travel through a medium.
What are some factors that were controlled by Surface Currents?
global winds, the Coriolis effect,
continental deflections, and the water
temperature.
What does The East Australian Current transports?
staggering 40 million cubic meters of water southward each second.
What is Continental Deflections?
If Earth's surface were covered only with water, currents would travel in a fixed pattern across the Earth, but Earth’s surface is not covered only with water. When currents meet landforms, they change direction. This is known as continental deflection.
Do Surface currents greatly affect the climate in many parts of the world?
YES!!!
True or False
Waves don't Transport Energy? Yes its True
False
Waves do transport energy
How far can Surface currents Reach Depths?
several hundred meters and lengths of several thousand kilometers.
How wide is the Current almost?
Almost 100 km wide
Where does Warm Water currents Being?
Near the Equator
Why do Cold-water currents create cooler climates in coastal areas?
Because other wise it would be much warmer like San Francisco.
What are Mechanical waves?
Are waves that require a medium.
What do Global winds blowing across the Earth’s surface create?
Surface Currents
How deep is the current?
more than 1.5 km deep – in fact, more like a ribbon than a tube.
What do currents do when they Meet Land forms?
They change directions
What does Some surface currents warm and some cool coastal areas year-round cause to change?
This causes changes in the atmosphere that disrupt the climate in many parts of the world.
What are Ocean Waves called?
Ocean waves are called mechanical waves because they travel through a medium.
True or False
The Gulf Stream is the shortest Surface Currents.
False
Where is another place it flows?
And it does flow southward from the Great Barrier Reef
True or False Earth’s surface is not covered only with water.
True
Is this True? Cold-water currents create warmer climates in coastal areas that would otherwise be much cooler (Iceland)
Nope
True: Warm-water currents create warmer climates in coastal areas that would otherwise be much cooler (Iceland)
Name 2 Examples of Waves?
There are lots of waves all around us in everyday life. Sound, Dropping rock in the pond to see the wave it makes, also in Microwaves
