Answer 2

Wave and tidal actions transport sand, pebbles, sea shells and gravel to the shorelines of oceans seas and lakes. The sand, pebbles, and gravels were either transported by erosion from the continental landmass by rivers and streams, or created by the mechanical weathering of wave actions against rock formations near the shore. Wind and storms can deposit the rock and shell particles further inland, creating a gently sloped beach.

Answer 3

When waves of long wave length and low height approach a gently sloping beach, the ellipse becomes horizontal. When the waves break, the swash sweeps up the beach as a sheet of water often reaching the upper beach. Most of the swash soaks into the beach which means that there is very little backwash. Waves of this type are called constructive or spilling waves.

From sand storms.
