WebRip currents are strong, narrow, seaward flows of water that extend from close to the shoreline to outside of the surf zone. They are found on almost any beach with breaking waves and act as “rivers of the sea,” moving sand, marine organisms, and other material offshore (see pictures below). Examples of different types of rip currents. WebAnswwer 9 Longshore currents form when waves approach the shore at an angle, causing the water and sediment to move along the shoreline parallel to the beach. This occurs because waves refract, or bend, as they approach the coast, and their energy is focused on the shoreline at an angle. highest obesity rate countries https://colonialbapt.org
