Chemical Sedimentary Rocks

Source/Author: David McConnell, Jennifer Wiggen
Subject: Chemical sedimentary rocks
Description: This video describes how various types of chemical sedimentary rocks form. We start by heating up some water in a pan to show you an analog for the formation of natural salt deposits. We discuss how small changes in water chemistry can result in spectacular rock formations like stalactites in limestone caves and travertine terraces associated with hot springs. Finally, we talk about how wood can be converted into a chemical sedimentary rock similar to those found in Petrified Forest National Park.
