What is the principle of original horizontality in geology?

• Sedimentary rocks are originally deposited in horizontal layers.

• Sedimentary rocks are originally deposited in vertical layers.

• Sedimentary rocks are originally deposited in circular layers.

• Sedimentary rocks are originally deposited in diagonal layers.

What does it indicate if sedimentary rock layers are tilted or folded?

• They were disturbed after formation.

• They were formed in a tilted position.

• They were formed in a folded position.

• They were originally vertical.

According to the principle of cross-cutting relations, if a rock or fault cuts through another, how does its age compare to the rock it cuts?

• It is older than the rock it cuts.

• It is the same age as the rock it cuts.

• It is younger than the rock it cuts.

• It is unrelated in age to the rock it cuts.

What does the principle of cross-cutting relations help us determine?

• The color of geological features.

• The relative ages of geological features.

• The size of geological features.

• The mineral composition of geological features.

What does the principle of original lateral continuity state about layers of sediment?

• Layers of sediment are deposited vertically.

• Layers of sediment initially extend laterally in all directions.

• Layers of sediment are always found in a single location.

• Layers of sediment are deposited in random patterns.

What is an unconformity in the geological record?

• A continuous sequence of rock layers

• A gap in the geological record

• A type of fossil

• A volcanic eruption

How does an unconformity form?

• Through continuous sediment deposition

• By volcanic activity

• When layers are eroded or not deposited for a period of time

• By earthquake activity
