, A., Right-side-up; you are looking at the side that was facing up toward the sky when the rock was deposited. B., Edge-on; the side that was facing up toward the sky when the rock was deposited is now facing toward the lower-left-hand-corner of the picture. C., Edge-on; the side that was facing up toward the sky when the rock was deposited is now facing toward the lower-right-hand-corner of the picture. D., Upside-down; you are looking at the side that was facing down toward the center of the Earth when the rock was deposited. E., Edge-on; the side that was facing up toward the sky when the rock was deposited is now facing toward the upper-right-hand-corner of the picture. A story is told here. Some mud was deposited, dried and cracked. The muddy-sandy layer we are looking at was deposited on top, and the brown ridges stuck DOWN into the cracks in the mud. After the rocks were hardened, this muddy-sandy layer was split off from the muddy layer below, and then turned over, so you are looking at the bottom of the layer now. , Points Earned:, 0/1 Correct Answer:, D Your Response:, B

, 7. , Look at the picture above which shows a region just less than a foot across, of a stream deposit from the base of the same pile of rocks that show up in Bryce Canyon.

A indicates a piece of limestone that has been rounded off in a stream; B indicates a mass of sand glued together by hard-water deposits, and C indicates another such mass of sand glued together by hard-water deposits . In order of time of formation, they are: , A., C was glued together by hard-water deposits, then A was formed, then B was glued together by hard-water deposits. B., A was formed first, then B was glued together by hard-water deposits, then C was glued together by hard-water deposits. C., C was glued together by hard-water deposits, then B was glued together by hard-water deposits, then A was formed. D., B was glued together by hard-water deposits, then C was glued together by hard-water deposits, then A was formed. E., B was glued together by hard-water deposits, then A was formed, then C was glued together by hard-water deposits.
