GEOLOGY

Detailed explanation-1: -Wind patterns and the rotation of Earth cause spiral or circular currents to form in the ocean. These currents are called gyres. An ocean gyre is a large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation.

Detailed explanation-2: -A gyre is a large system of rotating ocean currents. Together, these larger and more permanent currents make up the systems of currents known as gyres. Wind, tides, and differences in temperature and salinity drive ocean currents.

Detailed explanation-3: -Gyres are created by three forces: the rotation of the Earth, wind patterns, and the landmasses of the Earth. The wind blows across the ocean’s surface, causing the water to move in the direction of the wind. As part of the Coriolis effect, the earth’s rotation counteracts the movement of the wind.

Detailed explanation-4: -Gyres are spiraling circulations thousands of miles in diameter and rimmed by large, permanent ocean currents. Eddies are smaller, temporary loops of swirling water that can travel long distances before dissipating.
