Question

A key sign of submergence of coastal terrain is the pres of a. Estuaries b. Marine terraces c. Atolls d. Tombolos A metamorphic rock called gneiss is found inside a block of granite. Using the "Principle of Inclusion", which is older? a. Granite b. Gneiss c. Both are the same age d. There is no way to know which is older Imagine three layers of sedimentary rock that sit horizontally one on top of the other, like a layer cake. As you investigate further, you find that a fault has cut and offset the two lowermost layers, but doesn't cut and offset the top most layer. What scenario below is the most likely to have occurred in this situation? a. When the fault cut the layers, it didn't cut all the way to the top. It stopped cutting and offsetting just below the top layer. b. The top layer didn't exist when the fault offset the bottom layers. The top layer deposited after the fault cut and offset the bottom two layers. c. There is no way to tell what happened in this situation. A fault has cut layers of sedimentary rock. In determining the relative ages of the sedimentary layers and the fault, which principle do you ultimately need to use? a. Principle of unconformities b. Principle of inclusion c. Principle of cross-cutting d. Principle of superposition A fault cuts through a layer of shale. Which is younger? How do you know? a. The shale. Principle of inclusions b. The fault. Principle of inclusions c. The shale Principle of cross-cutting. d. The fault. Principle of cross-cutting.
