Explanation:

Each answer is based on core plate tectonics concepts:

1. Oceanic convergent boundaries form volcanic islands when one ocean plate subducts and melts, feeding volcanoes.
2. Oceanic divergent boundaries pull apart, allowing magma to rise and form mid-ocean ridges.
3. Continental convergent boundaries occur when two thick continental plates collide, pushing up to form mountains.
4. Transform boundaries involve plates sliding past each other, causing frequent, intense earthquakes.
5. Oceanic convergent boundaries form trenches when a dense ocean plate subducts beneath another plate.
6. When two plates converge, the denser plate (thinner oceanic plate) subducts under the less dense one.
7. "Converge" is defined as plates coming together.
8. Divergent boundaries pull apart, allowing magma to rise, melt, and create new ocean floor.
9. Plate tectonics drives both volcanic activity and earthquakes.
10. The deepest ocean spots are oceanic trenches, formed by subduction.
11. Volcanoes (from subduction or seafloor spreading) can form volcanic islands.
12. Tectonic plates are pieces of the Earth's crust that rest on the semi-fluid mantle.
13. Oceanic trenches are the deepest ocean environments, with extreme pressure where glow-in-the-dark fish live.
14. Subducting plates melt, and the magma rises to form new volcanoes.
15. Plate tectonics slowly shapes the planet, creates geologic features, and recycles crust.
