Longshore currents form because
a. waves hit the coast at an angle and form currents in the surf zone
b. beaches absorb waves and backwash in some areas of the coast
c. backwash leaves the shore with more energy than incoming swash
d. eroded material from the shoreline deflects currents parallel to the shore

A.     waves hit the coast at an angle and form currents in the surf zone
