Across
- 2. long, narrow excavation in the ground, typically deeper than it is wide
- 3. the biological process by which certain microbes (like bacteria and archaea) create energy and organic food by oxidizing inorganic compounds
- 5. a firm, white-fleshed fish known as "poor man's lobster"
- 7. the deepest, darkest, and highest-pressure part of the ocean
- 9. anything of, relating to, or produced by the sea or ocean

- 11. organic compounds found in bioluminescent organisms
- 12. the layer of the ocean extending from 200 to 1,000 meters (approx. 600–3,300 feet) below the surface
Down
- 1. hot water or the action of hot, aqueous solutions and gases, typically heated underground by the Earth's internal heat
- 2. the processes, forces, and resulting structures that form the Earth's crust, typically involving large-scale movements
- 4. a living organism that produces and emits its own light through an internal chemical reaction
- 6. the uppermost, sunlit layer of the ocean, extending from the surface to roughly 200 meters
