Stratified rock, also known as layered rock, is a type of rock that is formed through the process of sedimentation. This type of rock is characterized by its distinct layers, which are arranged in a parallel manner. A synonym for stratified rock is sedimentary rock, which is formed through the accumulation and compression of minerals and organic matter over time. Other synonyms for stratified rock include bedded rock, laminated rock, and banded rock. These terms refer to the distinct layers or banding patterns that are visible when the rock is broken open. Stratified rock can be found in many locations around the world and provides valuable clues to the earth's geologic history.
