WebOcean currents are produced by friction created by wind blowing over the water surface. However, the direction and speed of water currents do not match those of the wind … 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.

WebMar 28, 2007 · Along the shoreline at either end of such a segment, waves will approach at an angle, and currents (longshore drift) will be formed that flow parallel to shore and toward each other (fig. 22). The area in which the opposing currents eventually meet is known as a zone of convergence. Figure 22.
