Question

what type of stress occurs when plates move apart?
○ compression
○ faulting
○ shearing
○ tension

Explanation:

To determine the stress when plates move apart, we analyze each option:

• Compression: Occurs when plates push together, not apart.
• Faulting: Is a result of stress (like tension, compression, or shearing), not a type of stress itself.
• Shearing: Happens when plates slide past each other, not when moving apart.
• Tension: Is the stress that occurs when forces pull apart, which matches plates moving apart.

Answer:

D. tension (assuming the options are labeled A to D as: A. compression, B. faulting, C. shearing, D. tension)
