Here's a breakdown:
* Sedimentary rocks are formed from the accumulation and cementation of sediments. These sediments can be fragments of other rocks, minerals, or even the remains of organisms.
* Time and pressure play a crucial role in the formation of sedimentary rock. Over long periods, the weight of overlying sediments compresses the lower layers, forcing out water and air and causing the grains to become tightly packed together.
* Cementation occurs when minerals dissolved in groundwater precipitate between the sediment grains, acting like glue to bind them together.
Common examples of sedimentary rocks include sandstone, limestone, and shale.
