Review # 2 Marine

If you consider the ocean to have many different layers of water, identify where would you expect to find warm water heated by the sun:

• near the ocean floor

• near the ocean surface

• in a layer called the thermocline

• between 500 - 1000m

Why are there global winds?

• because the cold air sinks from the poles to the equator

• because the sun heats the air at the equator more than anywhere else on earth

• because the earth is rotating from east to west

How does the Coriolis Effect influence hurricanes and cyclones

• determines how powerful they will be

• determines where they form

• determines where they will go

• determines the direction of the wind rotation

______________ is the process in which deep, cold water rise towards the surface. It occurs in the open ocean and along coastlines. This water is typically colder and rich in nutrients.

________________ is the opposite of upwelling, it occurs when wind causes surface water to build up along the coastline and sinks to the bottom.
