Final answer:
Sandstone is a clastic sedimentary rock composed of sand-sized minerals, rock fragments, or organic material. During mountain building, sandstone comes into contact with other rocks or sediments. Spaces between the grains of sand are filled with minerals during a process called cementation.
Step-by-step explanation:
Sandstone is a clastic sedimentary rock composed of sand-sized minerals, rock fragments, or organic material. During mountain building, sandstone comes into contact with other rocks or sediments. Spaces between the grains of sand are filled with minerals during a process called cementation.
Once cemented, the sandstone becomes a hard, compacted rock. Examples of sandstone formations include the Ancient sedimentary beds of deep-red, pink, and white sandstones in the Garden of the Gods in Colorado and the sandstone from the Paleozoic of Ohio in the United States.
