GENERAL GEOLOGY

Detailed explanation-1: -The Law of Original Horizontality suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed. This allows us to infer that something must have happened to the rocks to make them tilted.

Detailed explanation-2: -According to the Principle of Original Horizontality, sediments are deposited horizontally. After they have been transformed into rock, strata may become tilted or folded by various tectonic movements. However, this principle basically states that “tilted or folded layers used to be flat”.

Detailed explanation-3: -The principle of superposition-in a vertical sequence of sedimentary or volcanic rocks, a higher rock unit is younger than a lower one. “Down” is older, “up” is younger. The principle of original horizontality-rock layers were originally deposited close to horizontal.

Detailed explanation-4: -Law of Horizontality As sediments deposit, they deposit in horizontal layers. This is known as the Law of Horizontality. The oldest layers are at the bottom and the newest layers are at the top. If you were to dig down through the layers, you would be going back in geologic time.

Detailed explanation-5: -Principle of cross-cutting relationships. The principle of cross-cutting relationships states that a rock unit (or other geological feature, such as a fault) that is cut by another rock unit (or feature) must be older than the rock unit (or feature) that does the cutting.
