Here's a breakdown:
* Sedimentary rocks are formed from the accumulation and cementation of sediments, which are tiny particles of rock, minerals, and organic matter.
* Wind and water are common agents that transport these sediments.
* Compression from the weight of overlying sediments and cementation by minerals dissolved in water bind the particles together, forming solid rock.
There are different types of sedimentary rocks based on the type of sediment:
* Clastic sedimentary rocks are made up of fragments of pre-existing rocks. Examples include sandstone (made of sand), conglomerate (made of gravel), and shale (made of clay).
* Chemical sedimentary rocks form when minerals dissolved in water precipitate out and crystallize. Examples include limestone and rock salt.
* Organic sedimentary rocks are formed from the remains of organisms. Examples include coal and oil shale.
So, in summary, rocks formed from layers of particles carried by wind and water are sedimentary rocks, and within that category, they are often clastic sedimentary rocks.
