Ocean Surface Currents
What do Surface currents flow like?
Rivers
Speeds in the core of the EAC are
among the strongest in the South Pacific, up
to --- mph an hour.
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. What is this known as?
Continental deflection.
Deep currents are -------- ---- movements of ocean water far below the ocean surface.
Stream Like
What two main components are waves made of?
Crest and Troughs
What 4 factors are Surface currents controlled by?
global winds, the Coriolis effect,
continental deflections, and the water
temperature.
The East Australian Current transports a staggering how many million cubic metres?
40 million
Warm water currents begin near the --------- and carry warm water to other parts of the ocean.
equator
Ocean water gets -------- when it becomes saltier or gets colder.
denser
Is a crest, the lowest point or the highest point?
highest
Surface currents can reach depths of several ----------- meters and lengths of several thousand ---------.
hundred
kilometres
The current is almost ------ km wide, and more than --- km deep- true or false?
100
1.5
Surface currents greatly affect the -------- in many parts of the world.
climate
Starting at a depth of about 200 meters, the water temperature becomes colder as the depth increases or Decreases?
increases
Is a wavelength the distance or vertical distance between a waves crest and trough?
Distance
Because of the Coriolis Effect, currents in the Northern Hemisphere turn ------------
clockwise
Where do Marlin and Nemo live?
The Great Barrier Reef
Some surface currents ----- and some ------ coastal areas year-round.
Warm and Cool
More or Less-dense water always flows on top of denser water.
Less
What are Mechanical waves?
Waves that require a medium.
Currents in the Southern Hemisphere turn -----------
counterclockwise
Is the East or West Australian current not the fastest flowing warp tube, in the movie?
East
Warm-water currents create warmer climates in coastal areas that would otherwise be much cooler, Iceland or San Francisco?
Iceland
Do deep currents carry colder or warmer water?
colder
What is a wave defined as?
A transfer of energy.
