Answer:
Superposition --- C. the oldest is on the bottom, the youngest on top.
Cross-cutting relationships --- B. faults, fractures are younger than the rocks they cut through.
Unconformities -- D. missing time
Original horizontality -- A . sedimentary layers/lava flows are deposited in flat layers.
Step-by-step explanation:
- The superimposition is the layering of the older beds of the sedimentary rocks and has a series of a layer of the lava flows with the oldest layer at the bottom and the youngest at the top.
- The cross-cutting is the principle of geology that states the which feature cuts the another or the younger of them and is a relative dating technique.
- An unconformity is a buried erosional or a non-depositional surface that is separating the two rocks masses or the stratas and thus indicates that the sediment deposits were not continuous.
- The principle of the horizontality states that the layer of the sediments is originally deposited horizontally under the action of gravity a thus this analysis helps in the folded and tilted strata.
