Question

which of the following are methods of relative aging of rocks? select the three correct answers. (2 points)
original angularity
angular relationships
radiometric dating
original horizontality
superposition
cross - cutting relationships

Explanation:

• Original horizontality: Sedimentary rocks are initially deposited horizontally. Deviations from this can help in relative - aging (e.g., folded rocks are younger than the folding event).
• Superposition: In an undisturbed sequence of sedimentary rocks, the older rocks are at the bottom and the younger ones are on top.
• Cross - cutting relationships: If a rock (or a geological feature like a fault) cuts through another rock, the rock that is cut is older.

Radiometric dating is an absolute dating method. "Original angularity" is not a standard principle for relative - aging. "Angular relationships" is a rather vague term and not one of the well - established principles of relative - aging like the three mentioned above.

Answer:

original horizontality, superposition, cross - cutting relationships
