Question

question 8 of 10
what do geological principles tell you about inclusions?
a. the layers of sediment on the bottom are the oldest.
b. layers that cut across the most other features are youngest.
c. fragments are older than the rocks they are inside of.
d. in a given region, all layers of sediment form at the same time.

Explanation:

To solve this, we analyze each option using geological principles:

• Option A: This describes the Principle of Superposition (oldest layers at bottom), not related to inclusions.
• Option B: This is about the Principle of Cross - Cutting Relationships (younger features cut older ones), not inclusions.
• Option C: The Principle of Inclusions states that fragments (inclusions) within a rock are older than the rock that contains them. This matches the concept of inclusions.
• Option D: Sediment layers form over time, not all at once, so this is incorrect.

Answer:

C. Fragments are older than the rocks they are inside of.
