Question

which rock feature is the line running between points a and b most likely to be? a. rock strata b. sill c. dike d. fault

Explanation:

To determine the rock feature between A and B, we analyze each option:

• Option A (rock strata): Rock strata are layers, but the line between A and B appears to be a fracture or displacement, not just layers.
• Option B (sill): A sill is a horizontal igneous intrusion, but the line here doesn't show horizontal intrusion characteristics.
• Option C (dike): A dike is a vertical or steeply inclined igneous intrusion, but the line between A and B looks like a fracture with displacement, not an intrusion.
• Option D (fault): A fault is a fracture in rock along which movement has occurred. The line between A and B likely shows displaced rock layers, consistent with a fault.

Answer:

D. fault
