Large bodies of water include oceans, seas, lakes, and rivers. These vast areas cover about 71% of the Earth's surface, with the Pacific Ocean being the largest. They play a crucial role in regulating the planet's climate and supporting diverse ecosystems. Lakes, such as Lake Superior, are significant freshwater sources, while seas, like the Mediterranean Sea, are partially enclosed by land. Rivers, including the Amazon River, are vital for transportation and irrigation. Together, these bodies of water provide habitats for countless species and are essential for human activities like fishing and recreation.
