Across
- 2. A liquid fossil fuel with a thick texture, found in deep underground deposits and made of many different hydrocarbons
- 4. Type of extraction seen after the initial pressure diminishes, in which case the water/gas is injected underground to push oil upwards to be collected
- 7. The energy of motion
- 10. Natural gas, cleanest burning of the fossil fuels
- 13. Formed when two small isotopes of hydrogen fuse together
- 14. The product of a rotating turbine making a generator move
- 15. Involves joining 2 atomic nuclei
- 17. A type of extraction in which natural underground pressure pushes the oil to the surface, requiring no additional action
- 19. An unstable atom and often emits a neutron
- 20. Readily available resources that are replaced quickly or continually
- 21. The energy required to move/change an object's position
Down
- 1. The energy emitted in the form of waves of the electromagnetic spectrum
- 3. Involves breaking-up an atom's nucleus
- 5. Resources which can never be replaced, or are replaced too slowly to be practical
- 6. Energy of an object due to its position/shape
- 8. The energy stored in chemical bonds between atoms and molecules
- 9. Type of mining used when coal deposits are deep underground
- 11. Energy associated with the movement/flow of electrons
- 12. The energy stored in forces holding atomic nuclei together
- 16. A very commonly used process for converting stored chemical energy into forms we can use for other things
- 18. The energy in the movement of molecules
