Rip currents are best described as water moving:

Rip currents are best described as water moving:

• A. alongshore parallel to the coastline.
• B. away from the shore in narrow channels.
• C. originating from submarine groundwater discharge.
• D. occurring only during high tides.

Answer: (B)

Rip currents are strong, narrow seaward flows that move water away from the shore through gaps in sandbars. They form when waves push water toward the beach but it must return to the sea through these confined channels, creating focused jets that run offshore perpendicular to the shoreline. This is different from alongshore currents, which move parallel to the coast, and from groundwater discharge, which is a subsurface process. Rip currents can occur under various wave conditions and are not limited to high tides.
