Terrigenous is a term used to describe material that originates from the Earth's surface. Some synonyms for this word include terrestrial, land-based, or earth-derived. These terms are often used in geology to describe the natural processes that lead to the accumulation of sediments on the Earth's surface. Other synonyms for terrigenous include detrital and clastic, which refer to sediments that are made up of broken-up pieces of rocks and minerals. These sediments are often transported by water or wind and are eventually deposited in new locations. Understanding the different terms associated with terrigenous sediments is important for understanding the natural history and geology of the Earth.
