3. Continuous physical force exerted on or against an object by something in contact with it
5. Relating to or produced by a volcano or volcanoes
8. Rock that has been transformed by heat, pressure, or other natural causes e.g. in the folding of strata or the intrusion of igneous rocks
10. The process of being liquified by heat
11. Includes all forms of modern life ever heard of (plants, mammals, dinos)
17. Rock having solidified from lava or magma
18. Layers of rock formed of fragments of other rock that was transported and deposited into water
19. A layer inside a planetary body bounded below by a core and above by a crust
20. The innermost geological layer of the planet Earth

1. A planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements
2. A material that is broken down by processes of weathering and erosion
4. The gradual destruction of a material due to wind, water, or other natural causes
6. Single-celled organism life explodes - beginning of plate tectonics
7. Photosynthetic Bacteria and multicellular organisms appear in fossil record
9. A layer or a series of layers of rock in the ground
12. Earth's transition from a protoplanet to an actual planet - giant fireball
13. Any preserved remains, impression, or trace of any once-living thing from a past geological age
14. Molten or semi-molten natural material from which all igneous rocks are formed; found beneath the surface of the Earth
15. The outermost solid shell of a rocky planet, dwarf planet, or natural satellite
16. Relating to the structure of the Earth's crust and the processes that take place within it
