ESS 101 INTRO TO GEOLOGY - University of Washington _ Laboratory 4: Volcanoes, Plutons, and IgneousRocks. Fall 2022. Score for this attempt: 11.9 out of 15. Igneous rocks form when magma cools, either slowly underground or rapidly at earth’s surface (i.e. near volcanoes). Magma cooling processes affect the size of crystals in igneous rocks. Bigger crystals form in slow-cooling, underground magma chambers, and smaller crystals form in fast-cooling lava flows/eruptions. To recognize eight common...
