| Aquifer | Large underground resevoirs for freash water. |
| Precipitation | Small water droplets in a cloud fform rain, snow, sleet and hail. |
| Percolation | Occurs when water is being pulled downwards through the soil. |
| Run-Off | Occurs when excess rain water of melt water can not be absorbed by the soil and overflows on the surface or drains into waterways. |
| Global Warming | Increasing the rate of melting of the polar ice caps, and icebergs. |
| White Snow and Ice | Reflects light |
| Dark Water | Absorbs light |
| Deforestation | In drier climates this can lead to desertification. |
| Climate Change | Is changing global patterns of precipitation |
| Benthos | Plants and animals that live in, on, or near the ocean bottom. Ex. kelp sponges, worms, claims, fungi, starfish, algae,snails,and sea urchins |
| Plankton | Small and microscopic organisims that move with the currents. Ex. kelp, algae, protozoa, jellyfish, some mollusks. |
