Across
- 4. the zone of the open ocean between 4000 and 6000m deep with near freezing temperatures and intense pressure which receives no sunlight. Also known as the aphotic zone.
- 5. smaller and less deep bodies of seawater that are partially enclosed by land; they are found where the ocean and land meet
- 7. a natural environment that absorbs carbon dioxide from the atmosphere faster than it releases it.
- 9. the zone of the open ocean between 0 and 200m deep which receives enough sunlight for photosynthesis. Also known as the photic zone
- 10. the combination of all major oceans into one large, interconnected body of water that encircles the world’s continents
Down
- 1. the zone of the open ocean between 200 and 1000m deep which receives very little sunlight. Also known as the disphotic or twilight zone.
- 2. the lowest depth region in any body of water including the surface of the substrate.
- 3. the community of organisms found in the benthic zone.
- 6. benefits people obtain from ecosystem, including food, flood regulation, climate control and water purification
- 8. a continuous mass of seawater on the Earth’s surface, its boundaries formed by continental land masses, ridges on the ocean floor or the equator
