Surface currents are a result of
A
Global Wind Patterns
B
Earth’s Rotation
C
Density
D
All of the above
Explanation: 

Detailed explanation-1: -The global pattern of prevailing winds is caused by the uneven heating of Earth’s surface. As prevailing winds blow across the ocean, they create surface currents in the water. Both prevailing winds and surface currents appear to curve due to Earth’s rotation. This is known as the Coriolis effect.

Detailed explanation-2: -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-3: -Coriolis Effect-the deflection of an object’s path due to Earth’s rotation. The prevailing winds of the world are produced by a combination of atmospheric convection currents and the Coriolis Effect.

Detailed explanation-4: -Large global wind systems are created by the uneven heating of the Earth’s surface. These global wind systems, in turn, drive the oceans’ surface currents.

Detailed explanation-5: -Global Wind Patterns. Wind is mainly the outcome of a thermodynamic principle and the Coriolis effect due to the counterclockwise rotation of the earth. Warm air around the equator is lifted, which creates a suction effect for air masses coming from higher (or lower) latitudes.
