Weathering & Erosion

WeatheringErosionWeathering & Erosion

In this CELL students investigate and model physical and chemical weathering. Additionally, students model erosion and the extent to which erosion can affect soil on a slope. In concluding this CELL, the students study various components of a model soil sample and investigate the size differences among the three components.

Investigation focus:

  • Recognize and investigate the differences between both physical and chemical weathering.
  • Model physical weathering and investigate chemical weathering of marble.
  • Model erosion of soil by water on a sloped surface.
  • Determine factors that increase and decrease erosion of soil.
  • Correlate the extent of soil erosion with differences in the slope of a surface.
  • Investigate the different components of a modeled soil sample and determine the differences between the components.
