Why do we have an Ocean?

Oceans cover about 71% of the Earth's surface and play a crucial role in regulating the planet's climate by absorbing carbon dioxide and heat from the atmosphere. They are formed through geological processes, including the movement of tectonic plates and volcanic activity, which shape the ocean basins. Additionally, oceans support diverse ecosystems and are vital for global weather patterns, as well as providing resources for human activities such as fishing and transportation.
