Answer:
Uplift raised the level of a piece of crust.
Mountains eroded.
Basaltic lava flowed from cracks in the crust.
Explanation:
A plateau can form in several different ways. It can form because of volcanic activity, the collision of plates, uplift of crust, and erosion.
Uplift that has raised a piece of crust can easily form this plateau. If the crust that is moving up is relatively flat at the top, then it will stick out in the surrounding area like a mountain will, but it will have a relatively flat top, thus making a plateau.
Erosion is very often a factor that creates plateaus. If there is a very large piece of crust that is much more solid than its surroundings, it will erode at a much slower rate. This will result in the crust around it to erode while it remains close to its initial form, thus sticking out as a higher relief form.
In the areas where there is or has been volcanic activity, it is common that plateaus as the one on the image are found. When the lava flows it fills in the valleys, cracks, holes, and when it solidifies it creates solid masses of igneous rocks. These rocks erode very slowly, so while all of the surroundings erode faster and lower down, it remains largely the same in the form of a plateau.

Answer:
Super position
Faunal Succession
Crosscutting Relationships
Inclusions
Explanation:
Superposition: The most basic concept used in relative dating is the law of superposition. Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it. This law follows two basic assumptions: (1) the beds were originally deposited near horizontal, and (2) the beds were not overturned after their deposition.
Faunal Succession: Similar to the law of superposition is the law of faunal succession, which states that groups of fossil animals and plants occur throughout the geologic record in a distinct and identifiable order. Following this law, sedimentary rocks can be “dated” by their characteristic fossil content. Particularly useful are index fossils, geographically widespread fossils that evolved rapidly through time.
Crosscutting Relationships: Relative ages of rocks and events may also be determined using the law of crosscutting relationships, which states that geologic features such as igneous intrusions or faults are younger than the units they cut across.
Inclusions: Inclusions, which are fragments of older rock within a younger igneous rock or coarse-grained sedimentary rock, also facilitate relative dating. Inclusions are useful at contacts with igneous rock bodies where magma moving upward through the crust has dislodged and engulfed pieces of the older surrounding rock.
