Question
To what direction do surface currents (gyre) flow between 30 degrees north and 60 degrees north?
Group of answer choices
- west
- down
- east
- south
- north
Solution
Answer:
Surface currents in the ocean, particularly in gyres, are influenced by the Coriolis effect, which arises from the rotation of the Earth. Between 30 degrees north and 60 degrees north, surface currents flow to the right of the wind direction in the Northern Hemisphere due to this effect.
-
Coriolis Effect: In the Northern Hemisphere, moving objects are deflected to the right. Hence, surface currents will also be deflected in this manner.
-
Direction of Flow: The wind patterns (trade winds and westerlies) contribute to the formation of gyres. The North Atlantic and North Pacific gyres, for example, show that surface currents in this latitude band flow generally towards the right of where they originate.
Given this understanding, the correct answer is:
Final Answer:
East.
