Across
- 5. Trench: a depression of the seafloor or the deepest part of the Earth's ocean that is long, narrow, and V-shaped
- 6. Boundary: a type of plate boundary that occurs when two plates move away or diverge from each other
- 7. Plates: Rigid, massive, and irregular slabs of the Earth's lithosphere (crust and upper mantle)
- 9. Boundary: a type of plate boundary that occurs when two plates collide with each other
- 10. Ridges - the largest, longest mountain range on Earth (around 65,000-70,000 km)
Down
- 1. the geological process that happens at convergent plate boundaries and occurs when oceanic crust (which is denser) sinks below continental crust (which is lighter)
- 2. Spreading: a geological process that occurs at divergent plate boundaries, especially around mid-ocean ridges, where the two plates separate and magma rises to create new ocean crust
- 3. Boundary: a type of plate boundary that occurs when two plates are moving sideways next to each other
- 4. a fracture in the Earth's crust that often causes earthquakes
- 8. Drift: the theory proposed by Alfred Wegener that said that the continents of Earth were once a supercontinent called Pangea, and they broke apart and drifted over the span of a million years
