- 2. rock formed from molten Earth material, such as granite or basalt
- 5. (breakdown) wear away or change the appearance or texture of (something) by long exposure to the air.
- 6. a part of a once living thing or a trace of an organism preserved in rock
- 7. (air) the layers of gasses surrounding a planet or other celestial body
- 10. rocks that form from preexisting rocks as the result of heat and pressure changes
- 15. a crack in the earth’s surface where movement has occurred; boundaries of plates
- 17. Large marsupial
- 18. Flying mammal
- 19. shaking of the Earth’s crust along the boundary of a plate
- 20. a solid sediment that is similar to dust; made up of fine sand, clay or other material carried by running water and deposited as a sediment
- 21. the process that happens when glaciers, running water, waves, or wind carry away the soil and rocks on the Earth’s surface

- 27. the upper layer of Earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay and rock particles.
- 28. is any naturally formed solid in the crust made up of one or more kinds of minerals
- 29. a naturally occurring mineral containing a valuable constituent such as metal for which it is mined and worked.
Down
- 1. an opening in a planet’s crust through which molten rock, hot gasses, and other materials erupt.
- 3. Has a trunk
- 4. rocks formed from the accumulation of sediment, that is squeezed and cemented together over time
- 8. the laying down of sediments by wind, water or glaciers
- 9. Man's best friend
- 11. a silvery-white metal
- 12. the energy that comes from heat
- 13. the second layer of the Earth located between the crust and the outer core

- 22. Likes to chase mice
- 24. a strong, hard magnetic silvery-gray metal
- 25. a natural material made up of tiny particles of rock; when mixed with water can hold its shape.
- 26. places where plates slide sideways past each other (slip past each other horizontally)
