| Precipitation | Water released from clouds, mainly in the form of rain. In a diagram, it is usually shown in a downward arrow starting from the clouds. |
| Evaporation | Process by which water changes from a liquid to gas. Heat energy is gained in the process. In a diagram, it is usually shown in an upward arrow. |
| Transpiration | The release of water from plant leaves. In a diagram it is shown by an upward arrow coming from the plants. |
| Condensation | Process by which water vapor is changed into a liquid. Heat energy is released in this process. Usually will see an arrow by a cloud to represent this process. |
| Runoff | Water that hits saturated ground and begins flowing over the landscape, usually ending in a body of water. In a diagram, this is represented by an arrow going over the ground. |
| What is the process that makes clouds | Condensation |
| Where is the majority of the Earth's water located? | In oceans |
| Where is the majority of Earth's freshwater located? | In glaciers and ice caps |
| which has more runoff --urban or rural? | Urban - the materials in cities (like concrete) are not porous so water can saturate into the ground as easily. |
| why does more evaporation occur over water compared to land? | There isn't as much water on land to evaporate. |
| what causes toxic algae blooms? | Fertilizer runoff, failure of septic systems, animal manure, runoff from power plants and waste treatment systems |
| factors that cause toxic algae blooms | warmer water, shallower water, |
| results of algae bloom | dissolved oxygen in water, dead fish, humans getting sick. |
| solutions for algae bloom | stop using fertilizer, snails, air-gators, etc |
