Question

Quizplus · Accepted Answer

Travertine is a chemical sedimentary rock, as it forms through the chemical precipitation of calcium carbonate from groundwater. It is not clastic, which forms from eroded fragments of pre-existing rocks, nor is it biochemical, which forms from the accumulation of organic material, such as shells or fossils. It is also not organic, which forms from the remains of plants and animals.
