This worksheet challenges students to apply the principles of relative dating to determine the sequence of geological events in two cross-section diagrams.

To solve the problems related to relative age in the provided images, we need to apply principles of geology, specifically the law of superposition, cross-cutting relationships, and intrusion/extrusion. Let's analyze each question step by step.

First Image:

#### 1. Layer A or Layer C
- According to the law of superposition, the oldest layers are at the bottom, and the youngest layers are at the top.
- Layer C is at the bottom, and Layer A is above it.
- Therefore, Layer C is older than Layer A.

#### 2. Layer C or Layer B
- Layer B is directly above Layer C.
- Using the law of superposition, Layer C is older than Layer B.

#### 3. Intrusion D or Layer A
- Intrusion D cuts through Layer A, meaning that Layer A must have been present before the intrusion occurred.
- Therefore, Layer A is older than Intrusion D.

#### 4. Layer A or Fault E
- Fault E cuts through Layer A, indicating that Layer A existed before the fault formed.
- Therefore, Layer A is older than Fault E.

#### 5. Intrusion D or Fault E
- Intrusion D appears to be intact and not affected by Fault E, suggesting that Fault E occurred after Intrusion D.
- Therefore, Intrusion D is older than Fault E.

Second Image:

#### 6. Layer H or Layer K
- Layer H is below Layer K.
- Using the law of superposition, Layer H is older than Layer K.

#### 7. Intrusion P or Layer H
- Intrusion P cuts through Layer H, meaning that Layer H must have been present before the intrusion occurred.
- Therefore, Layer H is older than Intrusion P.

#### 8. Layer M or the fragments in M
- The fragments in M appear to be derived from Layer M itself (likely due to weathering or erosion).
- Since the fragments are part of Layer M, Layer M is older than the fragments in M.

#### 9. Intrusion P or Layer Q
- Intrusion P cuts through Layer Q, indicating that Layer Q existed before the intrusion occurred.
- Therefore, Layer Q is older than Intrusion P.

#### 10. Layer H or the tilting of Q-L
- The tilting of Layers Q-L indicates a deformation event that occurred after these layers were deposited.
- Since Layer H is below Layer Q, it must have been deposited before the tilting event.
- Therefore, Layer H is older than the tilting of Q-L.
