Contrast groundwater and surface water. Groundwater

Surface Water

Distinguish erosion from deposition. Erosion the process of moving weathered material, or sediment, from one location to another

Deposition Water slows and drops sediment.

Connect It  Describe the ecoregion in which you live.

Accept all reasonable responses. Sample answer: I live in an ecoregion that is partly

grassland and partly forest. The weather varies dramatically by season, from cold

with moderate precipitation in the winter, to very hot and dry in the summer. The

plants and animals that live here are adapted to the weather extremes. Weather and Its Impacts
