ocean currents

QuestionAnswer
the surface currents in each ocean form circular systems of currents gyre
large volume of water flowing in a certain direction ocean current
vertical movement of water toward the oceans surface upwelling
movement of water to the right or left that is caused by earths rotation Coriolis effect
ocean currents affect the weather and climate
the oceans are a major part of the water cycle
the great ocean conveyor belt is a model used to explain how ocean currents circulate thermal energy around earth
the vertical movement of water toward the oceans surface is an upwelling
the vertical movement of water from the surface to deeper parts of the ocean is a density current
is the movement of water to the right or left and is caused by earths rotation the Coriolis effect
a grye is a circular system of currents
surface currents move water and extend to about 400 m below the suface horizontally
surface currents are caused by friction from the wind
is a large volume of water flowing in a certain direction an ocean currrent
surface currents move vertically and less than 400 m below the surface false/horizontally
density currents move water vertically toward the deeper parts of the ocean true
an up-welling moves water vertically toward the oceans surface true
ocean currents affect weather and climate by redistributing wind energy false/thermal energy
the oceans are the major source of moisture for the water cycle true
which two things do ocean currents transfer that affect weather thermal energy and moisture
where does up-welling occur on the model the indian and pacific ocean
what forms gyres in each ocean the coriolis effect
what affects the size of a gyre landmasses
list three factors that affect the flow of surface currents wind, energy, current
how are gyres in the northern and southern hemispheres diffrent the northern hemisphere goes clockwise and the southern hemisphere goes counter clockwise

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
