Episode 17: Sedimentary Rocks

 

The questions for those who want to copy into Word:

1. What are sedimentary rocks, and how are sediments formed. Be sure to discuss both mechanical and chemical weathering products.

2. How does energy affect the transportation and deposition of sediments. Why do we find sand at the beach?

3. Describe at least two sedimentary structures. Why are they important in deciphering earth history?

4. What is the difference between symmetrical and asymmetrical ripple marks, and how do they help us understand the depositional history of an area?

5. Summarize the geologic history of the Grand Canyon. Be specific and be sure to include rock types, ages, and thicknesses.
