Question 1005Navigation General

The correct answer is A) Surging. On a beach with a steep underwater slope, the waves will tend to surge up the beach rather than break. Surging breakers are characterized by a gentle, unbroken wave that rushes up the beach face without forming a white water crest. This is because the steep underwater slope causes the wave to lose its energy gradually, rather than abruptly breaking. The other options are incorrect because: B) Converging breakers occur on beaches with irregular shorelines, C) Spilling breakers happen on more gradual beach slopes, and D) Plunging breakers form on moderate beach slopes, but not the very steep slope described in the question.
