The planet known as the "Ocean Planet" is Earth. Approximately 71% of Earth's surface is covered by water, mostly in the form of oceans. These vast bodies of water play a crucial role in regulating the planet's climate, supporting ecosystems, and providing resources for human life. Oceans are home to a tremendous diversity of marine life, from microscopic plankton to massive whales, and they are vital for global weather patterns. Despite its name, Earth also has varying terrains, including mountains, forests, and deserts, but its oceans are essential for life as we know it.
