Presumably you mean rocks. Well, mountains erode into rivers, which take the eroded matter downstream and deposit them into the sea. This then forms a sea bed of sand, which compresses underneath more sand to form solid rock again. This rock is then usually pushed (by tectonic movement) into new land elsewhere. Thus the cycle starts again.
Rock armour works by stopping the sea erode the cliff behind it. It lets the sea erode the rock, protecting it from coastal erosion. As the rock is hard, it will last for many years - granite is perfect for this job.
They erode the land after thousands of years.
By erosion. Sea caves erode to become sea arches which erode to form sea stacks.

The two processes by which waves erode the land are impact and abrasion
The results of a lower base lever for rivers and streams is the sea level falls and the land rises. The base level is the level below which a stream cannot erode.
Usually waves erode land. Waves may form land if they push material from another location into a particular area. For example, the natural sea wall on Mt. Desert Island in Maine, was formed by such a process.
It only needs to erode to the highest point of a body of water, such as sea level.
water runoff causes erosion by beating the surface of the land
