GENERAL GEOLOGY

Detailed explanation-1: -The principle of original horizontality states that layers of sediment are originally deposited horizontally under the action of gravity. It is a relative dating technique. The principle is important to the analysis of folded and tilted strata .

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: -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-4: -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. This includes mountain building events, earthquakes, and faulting.

Detailed explanation-5: -Sedimentary rocks form with the oldest layers on the bottom and the youngest on top. Sediments are deposited horizontally so sedimentary rock layers are originally horizontal.
