Down
- 1. the scientific theory that Earth's continents slowly move across the planet's surface over geological time
- 2. a curved chain of volcanic islands formed at a convergent tectonic plate boundary, where one oceanic plate slides beneath another, creating magma

- 5. a long, narrow, and very deep depression on the seafloor
- 6. the Earth's longest mountain chain, an extensive underwater system formed at divergent tectonic plate boundaries where magma rises
