well .; sedimentary rocks are the type of rock that is formed by SEDIMENTATION of material at the Earth's surface and within bodies of water !.
sediment gets compressed together over long periodsmof time and with heat they get compacted into rocks
Not necessarily. There is a special class of sedmentary rocks, called sandstones, which are dominated by sand-sized grains. Other sedimentary rocks, such as shale, contain much finer grains.
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
by carol and size
Depends on how you categorize them. There are numerous types of rocks, and the number you come up with is just a representation of how specifically you classify them.
In classifying rocks, there are many properties that can be useful. In my opinion, either color or texture is most useful in classifying a rock or mineral.
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
