Скачать или смотреть Difference Between Rip Currents and Undertow

Rip currents and undertows are dangerous ocean currents that can occur at beaches and coastal regions. While many people use these terms interchangeably, they are actually different phenomena. Rip currents are outflowing currents of water that can pull swimmers hundreds to thousands of yards offshore. They are formed when large breaking waves rush up the beach and water seeks to balance itself by rushing back into the surfline. On the other hand, undertows are caused by the backwash of waves and can pull a swimmer underwater, but not out to sea. Undertows occur when a wave breaks on or near the shore and there is a large and fast-moving rush of water back down the beach. It is important to understand the difference between rip currents and undertows to ensure beach safety.
