SC15.4.15

Analyze and interpret data (e.g., angle of slope in downhill movement of water, volume of water flow, cycles of freezing and thawing of water, cycles of heating and cooling of water, speed of wind, relative rate of soil deposition, amount of vegetation) to determine effects of weathering and rate of erosion by water, ice, wind, and vegetation using one single form of weathering or erosion at a time.

Analyzing and Interpreting Data

Crosscutting Concepts

Cause and Effect

Knowledge

Students know:
  • Effects of weathering.
  • The rate of erosion of Earth's materials.
  • The kind of weathering or erosion to which the Earth material is exposed.
  • The change in shape of Earth materials as the result of weathering or the rate of erosion by motion of water, ice, wind, or vegetation.

Skills

Students are able to:
  • Represent data about weathering and erosion in tables and/or other graphical displays to reveal patterns.
  • Analyze and interpret data to make sense of weathering and erosion.
  • Compare and contrast data collected by different groups.

Understanding

Students understand that:
  • Events like weathering and erosion have causes that generate observable patterns and can be used to explain changes in Earth's landforms.
