The ocean is a vast body of saltwater that covers about 71% of Earth's surface. It is home to diverse marine life, including fish, mammals, corals, and microscopic organisms. The ocean plays a crucial role in regulating the planet’s climate, producing oxygen, and supporting global ecosystems. It is divided into five major oceans:

Pacific Ocean – The largest and deepest ocean.
Atlantic Ocean – The second-largest, separating the Americas from Europe and Africa.
Indian Ocean – Located between Africa, Asia, Australia, and the Indian subcontinent.
Southern Ocean – Surrounding Antarctica and influencing global climate patterns.
Arctic Ocean – The smallest and shallowest, covered in ice for most of the year.
