Across
- 2. boundaries when plates slip past each other
- 6. Drift Continents of the world were once joined together but over time have split and drifted apart
- 7. Known as the super continent
Down
- 1. boundary when plates move together or collide
- 3. one plate slips below another plate because it is more dense. The heavier plate is pushed down into the mantle. Causes deep ocean trenches and volcanoes to form
- 4. boundary when plates move away from each other or diverge
- 5. tectonics the outer layer of Earth is broken into many large and small plates. The continents and oceans ride on top of plates. The motion causes continental drift.
