Across
- 2. surface layer of the ocean with the most sunlight where photosynthesis takes place
- 5. a body of saturated rock or sediment through which water can move easily.
- 6. portion of land drained by a river and its tributaries
- 11. Warm, supports many producers and fish and marine life live here
- 12. under the photic zone from the continental shelf to the abyssal
- 13. the agency that sets maximum levels for safe drinking water, among other things.
Down
- 1. No light = no photosynthesis,rely on microbes that make their own food,can get energy through chemical bonds called chemosynthesis,hydrothermal vents are here and photic and bathyl zones are here
- 3. heat the amount of heat it takes to raise 1 gram of a substance by 1 degree celsius
- 4. the process of sending out sound waves to be reflected back off of objects that allows scientists to determine the location and shape of underwater objects
- 7. completely dark, receives no sunlight
- 8. vents driven by heat from volcanoes beneath the seafloor, chemical reactions take place as seawater flows through cracks in the seafloor to produce hot acidic fluids that rise.
- 9. includes photic zone, has the shoreline where light can the bottom because it is shallow, affected by tides and must be able to sustain winds and air, life exists here due to sunlight and photosynthesis
- 10. create organic matter using oxygen in seawater to get nutrients to organisms that don't receive light for photosynthesis
