Concept:A breaking wave produces two water movements on a beach, one moving landward and one returning seaward.
Explanation:When a wave breaks at the shoreline, its energy pushes a mass of water up the beach.
This forward rush of water, which is thrown up the beach slope, is called swash.
The swash carries sand and pebbles landward before its energy is spent.
After reaching its highest point, the water drains back down the slope.
This return flow of water is called backwash.
Undertow is a subsurface current that pulls water seaward below the surface.
Shore is the general land area bordering the sea.
Since the question describes water being thrown up the beach, the correct term is swash.
Answer:D. swash
