12.In the background, tourists walk along the rim trail in Bryce Canyon National Park. In theforeground, a small but still-living pine tree clings to its precarious existence overlooking one ofthe most glorious views on the planet. What is the history of this tree?A) Earthquakes shook the ground, shoving the tree up as the roots were squeezed by thecompressional, or p, waves.B) The tree grew in the normal way, with its roots underground, but rapid erosion washed thedirt away, exposing the roots.C) Several closely related seeds from a nearby pine tree sprouted here, and grew togethersymbiotically.D) An earthquake fault, like the Sevier Fault in nearby Red Canyon, dropped the canyon relativeto the rim trail, leaving the roots sticking out of the ground.E) The roots of the tree were excavated by the rare bark-biting Bryce beaver.13.In the photo above, what sort of rock is the dark material very close to the pink granite that Dr.Alley is pointing to?14.The picture above shows a view in the Earthquake Lake region just northwest of Yellowstone.The ramp or slope (often called a scarp) formed in an earthquake. What likely happened?A) Pull-apart forces shoved one side up over the other, making the break.B) Slide-past forces shoved one side up over the other, making the break.C) Push-together forces shoved one side up over the other, making the break.D) Pull-apart forces pulled the rocks apart, making the break, and allowing one side to droprelative to the other.E) Slide-past forces pulled the rocks apart, making the break, and allowing one side to droprelative to the other.
The next three (3) questions refer to the diagram above.This diagram shows a geologic cross-section of some rocks, such as you might see in a cliff. Thetree is growing on top of the modern surface. Rock layers A, B, C, D, E, and F are sedimentary; Econtains mud cracks and fossil footprints as shown. G is igneous rock that hardened from hot,melted rock. H, I and J are faults, and K and L are unconformities. Sedimentary rocks are right-side-up unless there is some indication given to show something else.Referring to the rocks you see here......
