Why do waves hit the beach at an angle?

When the waves approach the beach at an angle, The part of the wave that reaches shallow water first slows down the most, allowing some waves farther from shore to catch up. In this way, the wave is refracted (bent) so it hits the coast more nearly parallel to the coast.

a bar by coast rafting processThis happens because the waves meet on the beach at an angle and recoil perpendicular to the shore, causing the sediment to move down the beach in a zig-zag fashion. Spits are sedimentary landforms found near the coast. At one end, saliva connects to land and extends into the sea.
