4/1/19, 5:47 PMRockOn #10: GEOSC 10 Spring 2019, MergedPage 2 of 17The next four (4) questions refer to the diagram above.This diagram shows a geologic cross-section of some rocks, such as youmight see in a cliff. The tree is growing on top of the modern surface. Rocklayers A, B, C, D, E, and F are sedimentary; E contains mud cracks andfossil footprints as shown. G is igneous rock that hardened from hot, meltedrock. H, I and J are faults, and K and L are unconformities. Sedimentaryrocks are right-side-up unless there is some indication given to showsomething else.Remember that footprints and mudcracks tell you whether rocks are right-side up or upside-down, so look for those. Also, if a layer is upside-down, soare the layers that are in the same sedimentary pile, until you hit anunconformity. So, if you have layers Q, R, S and T in one sedimentary pilebeneath an unconformity, and then layer U above the unconformity, and youlearn that Q is upside-down, so are R, S, and T, but you must look for more
