What are the three categories of sedimentary rocks?
clastic rock formed from fragments broken off from parent rock, by
o weathering in situ or
o erosion by water, ice or wind
followed by transportation of sediments, to the place of deposition;
biogenic activity; or
precipitation from solution.
The sediments are then compacted and converted to rock by the process of lithification
This is from the second link above:
"There are three basic types of sedimentary rocks:
1) clastic sedimentary rocks such as breccia, conglomerate, sandstone and shale, that are formed from mechanical weathering debris;
2) chemical sedimentary rocks such as rock salt and some limestones, that form when dissolved materials precipitate from solution; and,
3) organic sedimentary rocks such as coal and some limestones which form from the accumulation of plant or animal debris."
