Constructive Response Question [ 3] 1. Draw a sequence of rock layers with the oldest rocks being sandstone, then shale and then limestone. Show folding and faulting. 2. Explain why some sedimentary rock layers may not always appear with the youngest rock on top and older rocks below. (As soon as we have about 5 questions students will be given a test on this material).
Answers 1. 2. Sedimentary rocks form in flat sheets that are disrupted by tension, compression and shearing of Earth’s crust. Folding and faulting results and alter the form of the layers.

Constructive Response Question [ 3] 3. Describe the similarities and differences between igneous, metamorphic and sedimentary rocks.
Answer Layering Crystals Igneous Does not show layering Variable, but small to large crystals are present and well mixed Sedimentary Most show layering Usually no crystals, if present are located inside cavities Metamorphic May or may not show Have crystals in layers or layering globs – not well mixed
Lab Directions • Pass out Lab Sheet. • Set up lap top computers. • Show students where to find the dichotomous key. • Warn students that the rocks and minerals are delicate and need to be handled carefully. Do not break or harm the minerals in anyway! • Pass out mineral kits. • We will do this again tomorrow.
