Weathering And Sedimentation
Channel: Earth Rocks!
Date: 2019-02-06

For an introductory college-level physical geology class: a review of weathering processes and products, depositional processes, and lithification of sediments. Includes a discussion of weathering vs. erosion; physical (mechanical) vs chemical weathering; dissolution, oxidation, hydrolysis, frost wedging, exfoliation, spheroidal weathering, and carbonic acid. Goes on to discuss the clues left behind in sedimentary rocks about the depositional processes at work during initial sediment formation, including graded beds, cross-bedding, and alluvial vs glacial deposits. Finishes with a review of how compaction and cementation turn these loose sediments into solid rocks.
