This assessment is a way to find our what your students actually understand about the three types of rocks. I have included questions about erosion and weathering to see if students understand the connection of rocks and weathering. There is not an answer key because the answers are based on the rocks that the students themselves choose to apply to the questions. The questions are foundational to common core based evidence questioning. Students should have their science text books, any reference material to find evidence to answer the questions. This can be used as a quiz, study guide, or actual test. I hope you find this product to challenge and enhance student understanding of rocks. Please look for my Just Minerals Assessment. It is designed in a similar format. Thank you again for purchasing my product.
