plate tectonic

3. Molten rock containing liquids, crystals, and dissolved gases that forms within the upper part of the Earth's mantle and crust.
4. Boundaries The zones where tectonic plates meet and interact.
7. A vent in the Earth's crust through which molten rock (magma or lava), gases, and ash erupt.
8. A ductile, partially molten layer of the Earth's mantle located beneath the lithosphere, allowing the plates to move.
9. Spot An area in the middle of a lithospheric plate where magma rises from the mantle and erupts at the Earth's surface.
11. An elevation, often long and narrow, found on the ocean floor at divergent boundaries.

1. The sudden shaking of the Earth's surface caused by the release of energy along faults where tectonic plates move.
2. The term used for magma once it has erupted onto the Earth's surface.
5. Tectonics The scientific theory that describes the motion and interaction of Earth's tectonic plates.
6. The rigid outer shell of Earth, composed of the crust and upper mantle, which is broken into tectonic plates.
10. A long, deep ditch on the ocean floor, often formed at subduction zones where one plate dives beneath another.
