Across
- 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
- 4. breaking down of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms
- 6. scientist who studies the solid, liquid, and gaseous matter that constitutes the Earth
- 9. forces build up features on the surface of the Earth
- 11. a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action
- 12. geological process in which sediments, soil and rocks are added to a landform or landmass

- 3. matter that settles to the bottom of a liquid
