| The BREAKDOWN and changes in rock and sediments at or near the Earth's surface produced by biological, chemical, and mechanical agents. | Weathering |
| The breaking down of rocks that changes the chemical composition of the rock through carbonation, hydration, and or oxidation. | Chemical Weathering |
| The breaking down of rocks into little itty bitty pieces by the changes in temperature, abrasion, and plant roots. | Mechanical Weathering |
| The process of which water, wind, ice, and gravity remove and transport or carry away sediments from one place to another. | Erosion |
| The Depositing of sediments and soil into a new location. (Deposit- Moving elsewhere) | Deposition |
| Area of LOOSELY packed soil that are saturated with water and located beneath the surface of the Earth. | Aquifers |
| Hazardous materials (such as pesticides, antifreeze, motor oil, paints) that enter the watershed and pollute the water. | Contaminants |

| Water that collects in cracks and pored underGROUND soil and rock layers. | Groundwater |
| Small pieces of rocks. | Sediments |
| Water on the surface of the Earth that comes from precipitation - Lakes, rivers, etc. | Surface Water |
| An area of LAND where the water that runs off the land drains into local rivers, streams, lakes and wetlands. | Watershed |
| An area below the surface where the ground is saturated with water. | Water Table |
