Oceans

Oceans cover more than 70% of Earth's surface and contain 97% of the planet's water. They play a

vital role in regulating global temperatures by absorbing and distributing heat. Oceans are also the

driving force behind the water cycle, producing most of the oxygen we breathe.

There are five major oceans: the Pacific, Atlantic, Indian, Southern, and Arctic oceans. Each has

unique ecosystems and marine life. For example, the Pacific Ocean is home to the Great Barrier

Reef, while the Arctic Ocean contains thick ice sheets and supports polar bears and walruses.
Ocean currents, driven by wind, temperature differences, and Earth's rotation, transport heat and

nutrients worldwide. These currents impact weather patterns and marine life distribution.

Despite their vastness, oceans face significant threats, including pollution, overfishing, and climate

change. Rising sea temperatures cause coral bleaching, while plastic waste endangers marine

animals. Efforts such as marine conservation zones, pollution control, and sustainable fishing are

crucial for ocean preservation.
