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.
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.
Obviously because they have some secrets they do not want people to know about.
Most of West Africa was colonized by France.
When water evaporates from its liquid form it changes into a gas. However, when water evaporates and becomes a gas it is no longer water (the name given to its liquid form) but is now considered water vapor. Water vapor is invisible and is lighter than air and for it to turn into water again must go through a process of condensation.
