Across
- 3. when two continental plates collide they create these
- 5. layer of earth that is a semi solid
- 6. organisms skin, flesh and bones decay slowly because of such cold temperatures
- 8. Currents-driving force behind plate movement
- 11. solid outermost layer of Earth
- 13. type of fossil that contains the organism
- 14. Alfred Wegner came out with this theory
- 16. when tectonic plates move past each other horizontally it creates this boundary
- 19. differentiation- how earth and other planets get their layers
- 22. type of rock most fossils are found in
- 25. type of seismic wave that travels through the crust only
- 26. organism becoming a fossil by being trapped in tar
- 27. geologic processes that never stop and help shape the Earth slowly
- 28. scientist that studies fossils
