When you observe an outcrop of steeply inclined sedimentary layers what principle allows you to assume that the beds became tilted after they were deposited?
Principle of cross-cutting relationships. by applying the cross-cutting principle, you can see that fault A occurred after the sandstone layer was deposited because it "broke" the layer..
What is a principle in stratigraphy?
In stratigraphy, a principle refers to a fundamental concept or guiding rule that helps identify and interpret the rock layers or strata within the Earth's crust. These principles are based on observations and empirical evidence. They include principles such as the law of superposition, which states that in undisturbed rock layers, the youngest rocks are on top and the oldest rocks are at the bottom. Other principles include the principle of original horizontality, principle of lateral continuity, and principle of cross-cutting relationships.
How do a geologist use the principle of superposition?
A geologist uses the principle of superposition to determine the relative ages of rocks and sedimentary layers. This principle states that in undisturbed layers of rock, the youngest layers are at the top while the oldest layers are at the bottom. By observing the order in which different rock layers are stacked, a geologist can infer the sequence of events that happened over time in a particular location.
Are reverse faults rock layers placed under tensional stress?
no, reverse fault rock layers are placed under compressional stress.
What scientific principle states that the earth's layers will be in chronological order?
The Principle of Superposition

What are the stratigraphic principles?
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest layer is on top and the oldest layer is at the bottom. The principle of original horizontality states that sedimentary rocks are originally deposited in horizontal layers. The principle of lateral continuity states that rock layers extend continuously in all directions until they thin out or reach a barrier. The principle of cross-cutting relationships states that any geological feature that cuts across a rock layer is younger than the layer it cuts through.
What do the principles of cross-cutting relationships teach us?
Layers that cut across the most other features are youngest.
Differences between a fault and a fold?
Folds are the when the rock layers bend. Faults are breaks in the rock layers. Folds are called anticlines and synclines. Faults are called reverse faults, normal faults, or strike-slip faults.
What is the relative age relationship of faults to the rocks they cut?
Because the rocks have to be there first, all faults are younger than the rocks they end up cutting across. In regard to sedimentary rock layers, each layer is younger than the one below it.
How are cross cutting relationships used in?
Cross cutting relations are used in relative dating because you can see which layers were deposited before or after the fault occured. The same way, when a fault cuts through a rock, or when magma intrudes and crystallizes, we can assume that the fault or intrusion is younger than the rocks affected.
Which is the correct answer for this questionThe law of ______states that new rock layers are always deposited on top of existing rock layers.?
New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
Faults can form in which layer of the earth?
Faults are formed at the outer solid layers of the Earth. They are developed within the earths crust or Lithosphere.

When rock layers break and resulting surface they break and slide on?
faults occur when this happens
Are reverse faults rock layers placed under tensional stress?
no, reverse fault rock layers are placed under compressional stress.
