Oceanic features refer to the various physical characteristics found in the world's oceans. These include structures like continental shelves, ocean basins, and mid-ocean ridges. The continental shelf is a shallow area near coastlines, while ocean basins are deeper regions that hold most of the ocean's water. Mid-ocean ridges are underwater mountain ranges formed by tectonic activity. Another important aspect of oceanic features is ocean currents, which are large-scale movements of water that influence climate and marine life. Additionally, coral reefs are vibrant ecosystems found in shallow waters, providing habitat for diverse species. Together, these features play a crucial role in Earth's environment.
