  1. Chapter 30 & 31 Review Prepared by Mrs. Senger

  2. Can you…? 1) What are the five groups of minerals and describe their characteristics? 2) What is a mineral? 3) What are the three kinds of magma and how are they the same/different? 4) What are physical tests we can run to test a mineral during identification? 5) What are the 3 kinds of rocks and what are their origins? 6) Describe the two kinds of metamorphism. 7) What are intrusive and extrusive rocks? 8) List the three kinds of volcanoes and their characteristics. 9) What is the rock cycle (deposition, cementation, chemical weathering, physical weathering, erosion, clastic rocks, fossils, and non/foliated rocks are all words you may choose to use in the description).
