Questions: surrounding host rock, the latter is older, as are any inclusions of the host rock found in the intrusion. The following illustration depicts an area and its underlying geology. Three points in time are depicted. - Time A: An igneous rock exists underground. - Time B: The ground surface is eroded, which exposes the igneous rock. - Time C: Layers of sedimentary rock are formed atop of the igneous rock. Using the principle of inclusions, rank the labeled areas from oldest to youngest. B. Exposure and weathering of intrusive igneous rock C. Deposition of sedimentary layers

Solution Steps

Step 1: Analyze the first image (Time A)

The igneous rock (A) intrudes into pre-existing rock (C). Since C is included _in_ A, C is older.

Step 2: Analyze the second image (Time B)

Erosion has exposed the igneous rock (A). The inclusions of rock (B) inside A mean that B is older than A.

Step 3: Analyze the third image (Time C)

Sedimentary layers (D) are deposited on top of the eroded igneous rock (A). This means A is older than D.

Final Answer:

From oldest to youngest: C, B, A, D
