PPT-Depositional Environments

Mud Cracks in Rock Current Environment What is a Depositional Environment All rocks form in specific environments An example of this that we talked about earlier are igneous rocks which are going to form in a volcanic area So it you find a layer of igneous rock you know that area once experienced volcanism .

Depositional rate depends on sediment size, shape and density.. Depositional rate also depends on characteristics of the depositional agent..

The spaces and places of our world are often divided and parsed out according to what they provide for humans. This may be an intangible, aesthetic provision, like a scenic vista or the presence of wildlife. Or, it could be utilitarian and related to a material and financial value. Humans often find themselves having to make a distinction between environments that we wish to conserve and protect, or freeze, and those that we wish to use and develop. From an urban neighborhood that sits precariously between the old and the new, to a small patch of forest that can be a nature reserve or the site of new homes, there resides a fundamental tension between change and preservation.
