Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What causes surface ocean currents to be deflected?
A
deep currents
B
the Coriolis effect
C
Earth’s revolution
D
global winds
Explanation: 

Detailed explanation-1: -The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect-a force that results from the rotation of the Earth-deflects them. The currents then bend to the right, heading north.

Detailed explanation-2: -But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.

Detailed explanation-3: -The Earth’s rotation causes the ocean currents to turn in a process known as the Coriolis effect . Because of the Coriolis effect, ocean currents deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Detailed explanation-4: -Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.

Detailed explanation-5: -Coriolis effect. noun. the result of Earth’s rotation on weather patterns and ocean currents. The Coriolis effect makes storms swirl clockwise in the Southern hemisphere and counterclockwise in the Northern Hemisphere.
