Across
- 2. plates move away from each other
- 4. Denser oceanic crust subducts (sinks) beneath lighter continental crust, forming deep trenches, powerful earthquakes, and
- 5. magma rises and cools down into a new oceanic crust
Down
- 1. Neither plate subducts easily; instead, the crust buckles and thickens to build massive non-volcanic mountain ranges
- 3. The older, denser oceanic plate subducts under the younger one, creating deep trenches and volcanic island
