| strip cropping | the practice of growing at least two different crops in the same field in alternating strips |
| cover crop | planting a crop in the fall, after harvest, to have plant cover on the bare field |
| grass waterway | planting grass in a constructed channel that carries runoff from a field (reduces erosion) |
| conservation tillage | no-till, strip-till, minimum-till, ridge-till, and sod planting (some kind of crop residue is left in the field to reduce erosion) |
| windbreaks | Eastern red cedar and loblolly often used to break up the wind (prevents erosion) |
| filter strips | planting strips of permanent vegetation to filter out pollutants (usually around bodies of water) |
| crop residue management | during harvest, cutting up and leaving unharvested remains on top of the soil to provide ground cover) |
| diversion | creating a channel across a hillside to divert runoff into an area where the water can be filtered before contaminating surface water |
| IPM | Integrated Pest Management |
| IPM examples | chemicals, mixing crops, or introducing natural predators |
| soil test | done to see exactly what nutrients are missing (so as not to apply excessive nutrients that could be carried by runoff and cause eutrophication in near-by waters |
| construction sites (soil erosion) | up to 150 tons per acre annually |
| agricultural sites (soil erosion) | 16 tons per acre annually |
| (rock cycle)sedimentary rock can become: | igneous rock or metamorphic rock; or loose sediment |
| (rock cycle) igneous rock can become: | loose sediments; or metamorphic rock |
| (rock cycle) metamorphic rock can become: | igneous rock; or loose sediments |
| (rock cycle) under pressure loose sediments can become: | sedimentary rock |
