Plate Tectonics
Across
- 1. the boundary between two tectonic plates that are moving away from each other
- 3. the layer of Earth between the crust and the core
- 6. the thin, outermost layer of the Earth
- 7. the theory that the Earth's lithosphere is divided into tectonic plates that move around on top of the asthenosphere
- 9. the outermost, rigid layer of the Earth that consists of the crust and the rigid upper part of the mantle
Down
- 2. the liquid layer of the Earth's core that lies beneath the mantle and surrounds the inner core
- 4. the soft layer of the mantle on which pieces of the lithosphere move
- 5. a break in the Earth's crust along which two blocks of the crust slide relative to one another
- 8. a piece of the lithosphere that moves around on top the asthenosphere
