11.3 Ocean Currents Quiz

How are density currents produced?

• water goes over the mountains, to erode the land, creating denser water

• A density current is produced when some water becomes denser, causing it to sink to the sea floor, and creating a current of the bottom of the ocean?

• when the denser water goes, and sink into the floor, and erupts again the in underawater volcanos

• denisty currents are produced by water becoming denser, with the salinated coral byproduct

What are the three Ocean currents that we learned today?

• Surface, Underwater, and Ground Water

• Surface, Upwelling, and Buoyancy

• Surface, Upwelling, and Density

• Deep Water, Primary Force, Secondary Force

How does an upwelling occur?

• When the surface water is pulled by the wind towards the land to make the dense water go further down

• the underwater volcanos create a bubble elevator for fishes to swim upwards

• The Density currents running below rise, and move the surface water upwards, creating higher sea levels

• When the surface water is pushed or deflected by wind, away from the shore, creating an open space for the dense water to rise

What are trade winds?

• winds where the currents go both ways and create a circle

• winds that travel parallel to the equator, and are created by the coriolis effect that blow westward

• winds that blow east in the polar regions.

• continents delfect the currents, causing the to trade with each other
