Ozeane are vast bodies of saltwater that cover about 71% of the Earth's surface. They play a crucial role in regulating the planet's climate and supporting diverse ecosystems. The five major oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean. These 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. The health of the oceans is essential for sustaining life on Earth.
