Across
  1. 2. Smallest particle; lots of these together make an element; two of these combined make a molecule
  2. 7. Two or more different atoms joined together
  3. 10. Organism (animal) that eats plants AND meat
  4. 11. Deepest part of the ocean floor; formed at a convergent plate boundary
  5. 13. Part of the ocean floor that drops steeply down; begins after the continental shelf
  6. 16. Cold water sinks and warm water rises to form these deep in the ocean; different salinities also cause water to move
  7. 18. More and more of something
  8. 20. ocean water movement that goes up and down on the surface of the water
  9. 21. Amount of salt in water
  10. 22. Two or more atoms joined together; may be the same atoms or different atoms
  11. 24. Ways an animal has changed in order to survive
  12. 26. Water moving in one direction near the surface of the ocean
  13. 27. Zone of the ocean that is the coldest, has the highest pressure, and no sunlight; animals have adaptations such as small eyes and light organs
  14. 31. How far the ocean floor is from the surface
  15. 32. Less and less of something
Down
  1. 1. Part of the food chain that eats producers or other consumers for energy
  2. 3. Chemical formula (another name) for water; tells you there are 2 hydrogen atoms and 1 oxygen atom
  3. 4. Producers in the ocean food web; often float near the surface of the ocean and make their own food by photosynthesis
  4. 5. Part of the food chain that gets energy from dead plants and animals
  5. 6. Organisms (animals) that eat meat
  6. 7. Land gently slopes underwater to begin the ocean floor; many living things are found here
  7. 8. Part of the food chain that makes their own food; examples include plants and phytoplankton
  8. 9. A famous surface current in the Atlantic Ocean off the east coast of the United States
  9. 12. People can change the ocean, in positive and negative ways
  10. 14. How much of something is in a space; for example, how much salt is in a liter of water
  11. 15. Organisms (animals) that eat plants
  12. 17. A lot of atoms that are all the same
  13. 19. Chemical formula (another name) for salt
  14. 23. Flat part of the ocean floor; the true bottom
  15. 25. Zone of the ocean that is cold, has medium pressure, and very little sunlight; animals often have adaptations like large eyes or ways to live in higher pressure
  16. 28. Ocean water gets higher and lower because of the gravitational pull of the moon
  17. 29. What we get from eating food; keeps us awake and able to think and do things
  18. 30. Zone of the ocean that is warm, has the lowest pressure, and lots of sunlight; most animals in the ocean live here
