Underwater landscapes are the diverse environments found beneath the surface of oceans, seas, and lakes. These areas can include coral reefs, rocky formations, sandy bottoms, and kelp forests. Each landscape supports a variety of marine life, from colorful fish to larger mammals like whales and dolphins. The structure of underwater landscapes is shaped by natural processes such as erosion, sedimentation, and volcanic activity. Features like seagrass beds and mangroves play crucial roles in coastal ecosystems, providing habitats and protecting shorelines. Understanding these landscapes is essential for marine conservation and biodiversity efforts.
