Final answer:
The world's ocean features five major gyres, which are large systems of circular ocean currents that have significant impacts on marine ecosystems and global climate.
Step-by-step explanation:
There are five major oceanic gyres on Earth. A gyre is a large system of rotating ocean currents, which are primarily driven by the Earth's wind patterns and the forces created by the rotation of the planet. The oceanic gyres are:
- The North Atlantic Gyre
- The South Atlantic Gyre
- The North Pacific Gyre
- The South Pacific Gyre
- The Indian Ocean Gyre
These large gyres play a critical role in the ocean's health and global climate, influencing marine ecosystems and the transport of oceanic debris.
