Currents and Waves

Ocean Surface(1&2)

100

Streamlike movements of water that occur at or near the surface of the ocean are called          .

Surface Currents 

200

Surface currents flow like      in distinct patterns around the Earth.

Rivers 

300

Surface currents are controlled by what four factors?

Global Winds, The Coriolis Effect, Continental Deflections, and The Water Temperature.

400

          blowing across the Earth’s surface create         .

Global winds and surface currents

500

Because of the Coriolis Effect, currents in the Northern                                 Hemisphere turn        while currents in the Southern                       Hemisphere turn          .

Clockwise and Counterclockwise

Nemo(3&4)

100

The East Australian Current transports a staggering          cubic metres of water southward each second.

40 million 

200

The current is almost           wide, and more than           deep

100 km and 1.5 deep 

300

The East Australian Current          flow along the East coast of Australia

does

400

Speeds in the core of the EAC are among the strongest in the South Pacific, up to        mph an hour

4.5

500

But actually the real East Australian Current is much        and much         than in the movie

Current Patternts(5&6)

100

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

200

Warm water currents begin near the      . 

Equator

300

Surface currents       affect the climate in many parts of the world.

greatly

400

Some surface currents         and some      coastal areas year-round.

Warm and Cool

500

This causes changes in the          that disrupt the climate in many parts of the world.

Atmosphere

Deep Currents(7)

100

         are stream-like movements of ocean water far below the ocean surface.

Deep currents

200

 Deep currents are        controlled by wind or the Coriolis effect.

not

300

Deep currents are mainly controlled by         in water density.

increases

400

Ocean water gets       when it becomes saltier or gets colder.

denser

500

 Starting at a depth of about         , the water temperature becomes colder as the depth increases.

200 meters

Waves(8&9)

100

A           is the highest point and the trough is the lowest point.

crest

200

 A       is the distance between two adjust crests or troughs

wavelength

300

          is the vertical distance between a waves crest and its trough.

Wave height

400

Ocean aves form because of          between the wind and the surface of the water.

friction 

500

 Waves move in a         pattern.
