Points Earned:1.0/1.03.What sort of rock is pictured above?A) Marmot #2B) Sediment that isn’t rock yet. The layers are alternating silt and sand from deposition from landslides off the Olympic Peninsula into the trench offshore.C) Igneous; The layers were caused by flow processes during the eruption that released this.D) Metamorphic; The rock separated into layers as it was cooked and squeezed deep in a mountain range.E) Sedimentary; The layering was caused by changes in the flow velocity of the river that deposited the material
Feedback: The large crystals, intergrown nature, and separate dark and light layers all point to metamorphism, deep inside a mountain range. Rapid cooling in volcanic eruptions gives tiny crystals, not the big, pretty ones here. You can see the former sand grains or other-sized pieces in sediment and sedimentary rocks. Andmarmot doo-doo consists of small, dark pellets, akin to big rabbit doots, and usually isn’t considered to be rock.Correct Answer(s):DPoints Earned:1.0/1.04.Tsunamis:
