Describing the Formation and Deciphering its History After we make observations, we can then take that information and develop ideas for what happened in order to explain what we see and even infer what must have happened under the surface. Stresses on and within the Earth cause rocks to deform, and rocks that experience extreme stress become permanently deformed. How this deformation happens depends fundamentally on the environmental conditions that the rocks are in when stressed. In low temperature and pressure regimes, rocks tend to deform in a brittle manner (e.g., they fracture and break). In high temperature and pressure regimes, they tend to deform in a ductile manner (e.g., they fold and change shape). Take a look at the Gigapan image and consider how you can apply what you have learned about various geologic principles to figure out the history of this outcrop. Use this approach to select the correct statements about the forces and events that contributed to this outcrop taking its current form. Select all that apply. ⺠View Available Hint(s) A subsurface fault displaced layers of rock that led to layers of sediment bending over the fault. Portions of the exposed layers of rock have eroded. This folding occurred under low pressure and temperature conditions. This folding was caused by humans drilling and blasting the rock to create a road. O Deep rock layers were deformed by a fault that did not reach the surface, which displaced the layers above and formed a monocline. Submit
