Geology Unit Rocks, Weathering, Erosion, and Soil

Geology Key Terms Erosion, including problems (Dust Bowl, landslides) and mitigation (contour plowing, terracing, mountainside netting) Abrasion Features from wind erosion (examples: dunes, Monument Valley) Features from water erosion (examples: canyons, v-shaped valleys, flood plains) Features from ice erosion (examples: u-shaped valleys, glacial lakes) Weathering: mechanical (including frost wedging), chemical, biological Mitigation strategies for beach erosion: artificial stabilization (groins, seawalls, breakwaters), beach nourishment, planting vegetation/beach grass

Geology Essential Questions What tectonic and geologic events formed North Carolina? Why does it become more difficult to reconstruct Earth’s history as we go back in time? How do barrier islands form? What factors influence the rate of weathering? What types of locations have the fastest weathering? What types of erosion move the largest sediments? Why should we care about erosion? What can we do to mitigate erosion? How can we tell if soil is well-suited for growing crops?
