Plate Boundaries-Clark

1. Large, rigid slabs of Earth's lithosphere (crust and upper mantle) that float and move atop the semi-fluid asthenosphere.
5. A major horseshoe-shaped belt around the Pacific Ocean characterized by frequent earthquakes and active volcanoes due to convergent boundaries and subduction zones.
6. Heat-driven cyclical currents in Earth's mantle that act as the primary engine moving tectonic plates.
8. An area where one tectonic plate is forced downward beneath another plate and into the mantle.
9. A zone where two plates collide, leading to mountain building, deep trenches, or subduction.
10. A zone where two plates move apart, allowing magma to rise and form new oceanic crust (like mid-ocean ridges

2. Sudden ground shaking caused by the release of accumulated stress and energy as rocks slip along fault lines.
3. A zone where two plates slide horizontally past each other, causing frequent earthquakes without creating or destroying crust.
4. Molten or semi-molten rock located beneath Earth's surface.
7. Vents or openings in the Earth's crust where molten rock, ash, and gases erupt to the surface.
