Explanation: Rocks are materials that are an essential part of the Earth's continuous crust and consist of aggregates of one or more minerals. In this rock concept, we include sand, gravel, volcanic ash, granite, sandstone, and so on.

All rocks follow a cycle, a continuous process by which old rocks are transformed into new ones. Thus, the rock cycle represents the various possibilities of transformation from one rock type to another.
