Answer 1

I can’t see the images for Q11 and Q14 — please upload them or describe what’s shown (direction of motion/arrows, ground movement, etc.). I can still answer the others and give identification tips for the image questions.

Identification tips
- Seismic waves: P waves = compressional (push-pull); S waves = shear (up-down or side-to-side, through solids only); Love waves = surface waves with horizontal side-to-side motion perpendicular to travel; Rayleigh waves = surface waves with rolling elliptical (vertical + horizontal) motion.
- Stress: Compression = arrows toward each other; Tension = arrows away from each other; Shear = arrows sliding past in opposite directions; Uniform = equal in all directions.

Answers
Q11: (image) — I can’t see the image; upload or describe it. Use the tips above to pick: Love (horizontal surface), Rayleigh (rolling), S (body shear), P (compressional).

Q12: D) At divergent boundaries in the middle of the ocean

Q13: B) Orogenic

Q14: (image) — I can’t see the image; upload or describe it. Use the stress-tip above to pick: Compression (arrows inward), Tension (arrows outward), Shear (opposite lateral arrows), Uniform (equal in all directions).

Q15: B) Water accumulated in the vent

Q16: A) Lateral

Q17: A) batholiths.

Q18: D) Isostatic equilibrium

Q19: D) Shield volcano

Q20: D) About every one million years (of the given choices — actual reversal intervals vary widely; on short timescales averages are much less, but 1 Myr is the closest option here)

If you upload the two images or describe them, I’ll give Q11 and Q14 definite answers.
