Here's a breakdown of the process:
* Sedimentation: Weathering and erosion break down existing rocks into smaller pieces called sediment. These sediments can be sand, silt, clay, pebbles, or even the remains of organisms.
* Transportation: Wind, water, and ice carry the sediments to a new location, like a riverbed, ocean floor, or desert basin.
* Deposition: The sediments settle out of the transporting medium and accumulate in layers.
* Compaction: As more layers of sediment build up, the weight of the overlying layers compresses the lower layers, squeezing out water and air.
* Cementation: Dissolved minerals in the water between the sediment grains precipitate and crystallize, acting like glue to bind the grains together.
Some common examples of sedimentary rocks include:
* Sandstone: Formed from cemented sand grains.
* Limestone: Formed from the accumulation of marine organism shells.
* Shale: Formed from compacted clay.
* Conglomerate: Formed from cemented gravel and pebbles.
