Unit 1: Water on Earth

2. pieces of ice that break off from glaciers that move by floating on the ocean
7. permanent movement of water that flow as "rivers" through the ocean, which is caused by wind and differences in temperature
9. abiotic factor found in lakes and oceans, which decreases the deeper down we go due to the lack of sunlight
10. zone in the ocean where light is visible, down to the first 200 meters
14. non-living organisms such as soil, temperature, water, and so on
15. how deep lakes are, in contrast to deep oceans
17. zone in the ocean where light begins to disappear
18. movement of water created by the gravitational pull of the Sun and the Moon
19. water movement around the environment through evaporation, precipitation, and condensation
21. large body of saltwater that serves as a habitat for a wide range of living species

1. zone illuminated zone near the coast of lakes and oceans, with plenty of oxygen
3. total amount of water on Earth, regardless of its physical state
4. movement of water on the surface of the sea caused by the wind
5. type of water containing high concentrations of salt which is unsuitable for humans and animals to drink to
6. type of water with a low concentration of salt, and used for drinking and cooking
8. type of diagram that shows similarities and differences between two topics
10. abiotic factor found in lakes and oceans, which increases the deeper down we go into them
11. body of water that constantly flows from high to low points
12. large body of permanent ice
13. living organisms that make up ecosystems, such as plants and animals
16. open-water zone found in lakes
20. body of water surrounded by land
