Across
- 5. A fracture in the rocks of Earth's crust
- 6. Occurs along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart
- 8. The movement of continents resulting from the motion of tectonic plates
- 12. Type of rocks that have been changed by intense heat or pressure while forming
- 18. The theory that Earth's outer shell is divided into several plates that glide over Earth's mantle
- 20. Type of rock formed by the accumulation or deposition of mineral or organic particles at Earth's surface
Down
- 1. A series of processes that create and transform the types of rocks in Earth's crust
- 2. Occurs at mid ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge
- 3. A chain of islands that forms from volcanic activity along a subduction zone
- 4. The study of the Earth's magnetic field preserved in rocks
- 7. Occurs when 2 plates slide past each other horizontally
- 9. A geologic structure formed by layers or beds of rock being bent or folded
- 10. A boundary where 2 tectonic plates move away from each other
- 11. The solid, outer part of Earth
- 13. Consists of partially molten rock and lies beneath the lithosphere
- 14. A boundary where 2 or more tectonic plates collide
- 15. Type of rock that is formed when molten rock cools to a solid state
- 16. The deformation of a material from stress
- 17. The rising or settling of a portion of the Earth's lithosphere in order to maintain equilibrium
- 19. Changes in the shape or position of rocks
