cosmogenous sediments
WebThere are four basic sources of such sediments-rocks, organic materials, water, and the cosmos. In fact, the fundamental classification for marine sediments is based on their origin. The following classification of the marine sediments is, therefore, based on the basic sources: (a) Lithogenous Sediment (c) Hydrogenous Sediment. WebLithogenous= composed of weathered fragments of pre-existing rock material, transported to the ocean by rivers, glaciers or wind 2. Biogenous= composed of hard remains of once- living organisms 3. Hydrogenous= formed when dissolved materials come out of solution (precipitate) 4. Cosmogenous= derived from outer space Web5 apr. 2024 · According to Collins dictionary, " Sediment is a solid material that settles at the bottom of a liquid, especially earth and pieces of rock that have been carried along and then left somewhere by water, ice, or wind."
