What are the similarities and distinctive features of continents and islands?

The mainland and the island are separate areas of land in the middle of a body of water. They can be of various shapes, but walking along the coast, after some time you will definitely come back. The continents are much larger and stand on separate tectonic plates that move very slowly relative to each other. The islands are often the peaks and plateaus of underwater mountain ranges. They also, unlike continents, can appear in the middle of freshwater lakes, rivers and reservoirs.
