text: you suspect that a rock you have found is sedimentray rock what features would you look for to confirm your? indentification grains that have been cemented together. can sometimes be rubbed off easily.  easily friable. (breaks off in small pieces)  layering due to deposition. (ie shale is in layers)  dull, earthy appearance.  no crystal formations. (unlike meta. & ign.)  fossils. (ie fossiliferous limestone; metamorphic may have some "warped" unidentifiable fossils but more than likely won't; it is impossible for ign. rocks to contain fossils b/c of complete melting of rock)
