The seafloor, also known as the ocean floor, is the bottom surface of the ocean. It consists of various geological features, including mountains, valleys, and plains. The seafloor is covered with sediments, which are made up of particles from land, marine organisms, and minerals. The study of the seafloor is important for understanding marine ecosystems and oceanography. It plays a crucial role in the Earth's climate and is home to diverse life forms, including coral reefs and deep-sea creatures. Scientists use tools like submersibles and sonar to explore and map this underwater landscape.
