Waves erode a coast by their continuous and repeated actions of swarsh\uprush and retreats\backwash.
Waves erode the coast through hydraulic action (the force of the water itself), abrasion (rock fragments carried by the waves), and corrosion (dissolving rocks like limestone). Over time, these processes wear away the coastline, shaping it through the removal of sediments and rocks.
Waves erode the coast by their constant beating against it, especially when storm surges and high tides occur together. If sea levels continue to rise through global warming, then the waves will be higher and perhaps more powerful. When this happens to cities and towns there is the danger that many homes will be destroyed.
The two processes by which waves erode the land are impact and abrasion
Waves erode approximately 1-2 feet of land from the coast of the US each year. This erosion can vary depending on factors such as the type of coastline, wave energy, and human interventions like seawalls.
Wave-cut cliff
Waves cause erosion through impact by carrying sediments and smashing them against the coast. They also erode through abrasion, where sediments carried by waves grind against the coast, wearing it down over time.
Two results are:A sea arch,when waves erode a layer of softer rock that underlies a layer a hard rock.Another one is a sea cave,which is formed when ocean waves hit against a steep and rocky coast lots of times.
When waves erode through a cliff, they produce sediments such as sand, gravel, and rocks. These sediments can be carried away by the waves, deposited on beaches, or transported to new locations by currents. Over time, the continuous erosion can lead to the formation of sea caves, arches, and stacks along the coast.

Ocean waves are what causes weathering and erosion on the coast. The force of the waves can create cracks in rocks and break them apart into smaller rockogjswziys.
