How waves form
Ocean waves contain energy, sometimes a large amount of energy. These waves are created by ocean winds, the winds carry the energy to vast distances across the pacific ocean. The energy in waves comes from wind that blows across the waters surface. Even breezes can cause small waves in lakes and ponds. A wave will change as it move towards land. In deep water, a wave only affects the water near a surface. As the wave nears the surface it drags on the bottom.
Erosion by waves
Waves are the major force of erosion along coasts. Wave shape the coasts through erosion by breaking down rock and transporting sand and other sediment. A way waves can erode the land is impact. Large waves can hit rocks really hard and over time it will break the rock. Waves also erode by abrasion. As a wave starts to come into contact with shallow water it picks up sediment including sand and gravel. The energy of these waves is concentrated on headland. A headland is a part of the shore that sticks out into the ocean. When waves a waves hits a steep rocky coast they will smash into the area again and again after a awhile this will end up into creating sea stacks,sea arch's, cliffs, sea caves, and wave-cut cliff.
Deposits by waves
Waves can coast when they deposits sediment, forming coastal features such as beaches, spits, and barrier beaches. Most of the deposition occurs when a waves gradually slows, causing the water to drop the sediment. As a waves reaches the shore, the waves drop sediment that they were carrying, forming a beach. A beach is an area of wave washed sediment along a coast. Sediment on beaches is mostly sand. waves that come to the shore come on an angle rather than straight on. As a wave repeatedly hits the beach, some of the beaches sediment move down the the beach with the current, in a process called long shore drift. a result of a long shore is a spit . A is a beach that projects like a finger out into the water. Most Spits often occur where a headland or other obstacle interrupts long shore. Incoming waves carry sand and build up to make huge sandbars, long ridges of sand parallel a barrier beach forms when storm waves pile up.
