About 75% of the rock outcroppings on continents are sedimentary rocks. Detrital sedimentary rocks are those for which the material has been transported as solid particles. The particles themselves may have derived from either physical weathering or chemical weathering. Sedimentation means settling from a fluid, either water or air.
An anesthesiologist is a medical doctor who keeps a patient comfortable, safe and pain-free during surgery by administering local or general anesthetic.
