Science Definitions

3. change in state from a liquid to a gas (ex.liquid water to water vapour)
5. a large mass of ice and snow that slowly flows over land
9. the concentration, or amount, of dissolved salts, in water.
12. areas where fresh water from rivers and salt water from the oceans mix to make somewhat salty or brackish water.
13. water that has gathered in clouds and falls to earth as rain, hail, sleet, or snow.
15. cycle : the movement of water as it changes states around Earth.
17. an underwater mountain.
18. a change in state from a gas to a liquid (ex. Water vapour changing into liquid water)
20. the distance between the crest of one wave and the crest of the next.

1. Small rivers and streams that join a larger River
2. Mixing of the upper and lower levels of the body of water, usually caused by a convection current.
4. a measure of the number of different types of organisms in an area
5. The circular flow of ocean water is composed of several major currents.
6. a layer of clay, silt, or rock where water can’t move through quickly/easily.
7. a natural depression in the ground where water can gather.
8. the process of water seeping through the earth.
10. large gathering of underground water in soil or rock.
11. an area surrounded by high land on which all water runs to a common destination.
14. water that flows along the surface of the ground.
16. a large ocean wave caused by earth movement or a volcanic eruption on the ocean floor.
17. a direct change in state from a solid to a gas (ex. Snow and ice on the surface of a glacier that changes directly back into water vapour).
19. A volcanic island with an eroded top that lies below the surface of the ocean.
