Across
  1. 3. The process where one tectonic plate sinks beneath another at a convergent boundary.
  2. 6. A small, steep volcano built from ash, lava fragments, and tephra.
  3. 9. A change in Earth's magnetic field where the north and south poles swap positions.
  4. 12. A tectonic plate boundary where two plates collide, often forming mountains or trenches.
  5. 14. A mountain formed when large rock blocks move along faults due to tectonic forces.
  6. 16. The force exerted by a sinking oceanic plate that helps drive plate movement.
Down
  1. 1. A line on a map or diagram showing regions of equal age, often used in geology.
  2. 2. A small tectonic plate that moves independently or interacts with larger plates.
  3. 4. A large depression formed after a volcanic eruption when a volcano’s summit collapses.
  4. 5. The process of mountain formation through tectonic plate collisions or movement.
  5. 7. A tectonic boundary where two plates slide past each other, causing earthquakes.
  6. 8. A body of intrusive igneous rock that cooled and solidified beneath Earth's surface.
  7. 10. The slow movement of continents over time due to shifting tectonic plates.
  8. 11. A low-lying region formed when tectonic plates move apart, often found at mid-ocean ridges.
  9. 13. The balance between Earth's crust and mantle, where land rises or sinks due to weight changes.
  10. 15. A massive lava flow covering large areas, forming thick basalt layers.
