Across
  1. 3. Currents Circular currents in the asthenosphere where hot magma rises and cooler magma sinks, acting as the driving force that moves tectonic plates.
  2. 9. The semi-fluid, ductile layer of the upper mantle directly beneath the lithosphere. Tectonic plates "float" and glide atop this layer.
  3. 10. An opening in Earth's crust where molten rock, ash, and gases erupt, usually found along convergent and divergent boundaries.
  4. 11. The rigid outermost layer of the Earth, encompassing the crust and the topmost solid mantle.
  5. 12. The physical property that dictates which plate sinks; older, colder, and oceanic crust sinks, while lighter, thicker continental crust stays on top.
  6. 14. separating
  7. 15. Melted rock beneath the Earth's surface, generated by the intense heat and friction of subducting plates.
Down
  1. 1. are the edges where the Earth's massive tectonic plates meet
  2. 2. Zone Where two continental plates crash into one another, buckling and pushing the rock upward to form immense mountain ranges (like the Himalayas).
  3. 4. sliding past each other
  4. 5. Zone A region where a denser oceanic plate slides under a lighter continental or oceanic plate.
  5. 6. colliding
  6. 7. A deep, steep-sided depression in the ocean floor formed at subduction zones.
  7. 8. Plates Massive, irregularly shaped slabs of solid rock that make up the Earth's lithosphere.
  8. 13. A sudden shaking of the ground caused by the release of energy when tectonic plates get stuck and slip past one another.
