Science – Max observed various rock formations. Then he identified how the rocks were formed such as the type of weathering, erosion, and deposition. Next Max reviewed how sedimentary rocks form when sediment is deposited, compacted, and then cemented together. Then he reviewed how metamorphic rocks are formed from extreme heat and pressure. Next he reviewed how igneous rocks are formed from either intrusive or extrusive volcanic activity. He took a test on rock formation and identification.
