GEOL 101 Lecture Notes - Lecture 7: Clastic Rock, Suspended Load, Bed Load
Document Summary
Sedimentary rocks are composed of particles that are the product of weathering or erosion of other rocks, including other sedimentary rocks, by wind, ice, and water. They are then deposited elsewhere in an orderly manner by the same agent. Sedimentary rocks are divided into two broad categories based on the environment they are deposited in. Marine : sediments deposited in and from the actions of sea water. Terrestrial : sediments deposited on the land, including freshwater lakes. Sedimentary rocks can be divided further precursor rocks. Clastic : deposited particles derived from the weathering and erosion of. Chemical/biochemical : precipitated by a variety of organic and inorganic. Bed load : material bounces (saltation) or rolls along stream bed. Suspended load : material suspended in water column; may become part of bed. Dissolved load : material is chemically dissolved in water; cannot settle out- load if stream velocity decreases must precipitate out. Basic precepts or guiding principles of sedimentary rocks.
