This page has links to photographs of different sedimentary environments and the rocks and deposits they form.  For each environment below, first click on the two small images of the modern-day environment and make observations about what you see, filling in the appropriate spaces in the table (Worksheet 5A in ASU lab manual or handed out by your instructor at Glendale CC).  Then, click on the small images of the rocks and deposits for that environment.  Do this for each environment in turn.

If you are accessing this via a modem and telephone line, beware because some of these images are large.  If you are accessing it from ASU or another fast network, don't worry, be happy, click away!
