Can you explain how these different coastal areas were formed?

All of the coastal areas have one thing in common, the land platforms were formed by the oceans waves. The waves had disintegrated the shore causing its shape and size, which will change more over time.

Ifound this on google “solar system formation. scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). this explosion made waves in space which squeezed the cloud of gas and dust.” i hope this you for what your looking for.
