Across
- 3. Spreading Process at mid-ocean ridges where new oceanic crust is created by magma.
- 4. Plate Massive irregularly shaped slabs of solid rock that make up the lithosphere.
- 5. The plastic partially molten layer beneath the lithosphere on which plates move.
- 6. The rigid outer shell of Earth including the crust and upper mantle divided into tectonic plates.
Down
- 1. Convection Hotter magma rises while cooler denser magma sinks driving plate motion.
- 2. Boundary Area where two plates collide forming mountains or subduction zones.
