The term "Ocean Sea" often refers to vast bodies of saltwater that cover more than 70% of the Earth's surface. These oceans are divided into five main areas: the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean. They play a crucial role in regulating the planet's climate and supporting diverse ecosystems. Oceans are home to a wide variety of marine life, including fish, mammals, and coral reefs. They also provide resources such as seafood and minerals, and are vital for global trade and transportation. Understanding and protecting these ecosystems is essential for maintaining biodiversity and the health of our planet.
