A.Composition-refers to the minerals of rocks that are formed.B. Texture-the shape, size, arrangement,
and distribution of the minerals that make up rocks
Rock Categories cont…• Sedimentary rock-Formed from
cemented sediments, minerals, or rock fragments. Have 3 categories:
Rock Categories cont…• • Clastic rocks- are made of
fragments of previously existing rocks. Examples: breccia and sandstone
Rock Categories cont…• Organic rock- come from organisms-
they are formed either directly or indirectly from the material. Examples: Chalk and limestone
Rock Categories cont…• Chemical rock-formed when a sea or
lake dries up, leaving large amounts of minerals that were dissolved in the water. Examples: Rock salt and gypsum
Rock Categories cont…• Metamorphic Rock-Formed from already existing rocks are
buried deep with in the Earth, that is effected by tremendous heat , great pressure, and chemical reactions.
