The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary metamorphic and igneous. … The rock cycle explains how the three rock types are related to each other and how processes change from one type to another over time.
What does vesicle mean in science?

Sedimentary rock is classified into two main categories: clastic and chemical. Clastic or detrital sedimentary rocks are made from pieces of bedrock sediment derived primarily by mechanical weathering. … Clastic rocks are classified by grain shape grain size and sorting.
