What is the geologic Law of Original Horizontality?
Law of Superposition Law of Cross-Cutting Relationships Law of Original Horizontality The correct chronological order for these laws is: 3. Law of Original Horizontality Law of Superposition Law of Cross-Cutting Relationships
They were deposited horizontally and then shifted by a geologic event.
The law of original horizontality states that sedimentary layers are initially deposited in horizontal layers due to gravity. Any deviation from this horizontal orientation indicates subsequent geological changes, such as folding, faulting, or tilting. This principle is crucial for understanding the relative age and history of rock layers in geology.
the law of original horizontality states that most sediments, when originally formed, were laid down horizontally. However, many layered rocks are no longer horizontal. Because of the Law of Original Horizontality, we know that sedimentary rocks that are not horizontal either were formed in special ways or, more often, were moved from their horizontal position by later events, such as tilting during episodes of mountain building.
the Law of Original Horizontality states that sedimentary layers and lava flows were originally deposited as horizontal sheets. However, they may not be horizontal or flat because they have since been displaced by various movements of the Earth's crusts, and geologists must find out what happened to cause these movements.

The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.

Stratigraphy is the study of the order and position of layers of archaeological remains. Its four principles are: law of original horizontality, law of superposition, law of original lateral continuity and law of cross-cutting relationships.
Law of Superposition: In an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top. Law of Original Horizontality: Sedimentary rocks are deposited in horizontal layers. Law of Cross-Cutting Relationships: Any rock layer or geologic feature that cuts across another rock layer is younger than the rock layer it cuts across.
It is called the 'Principle of Original Horizontality' and was proposed by the Danish geological pioneer Nicholas Steno (1638-1686). This principle states that layers of sediment are originally deposited horizontally. However, please note that it is now known that not all sedimentary layers are deposited purely horizontally and the principle is only an approximation of reality.
the law of super position basically says, "Sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top."
