Use evidence from a given landscape that includes simple landforms and rock layers to support a claim about the role of erosion or deposition in the formation of the landscape over long periods of time.
- Clarification Statements:
- Examples of evidence and claims could include rock layers with shell fossils above rock layers with plant fossils and no shells, indicating a change from deposition on land to deposition in water over time; and a canyon with rock layers in the walls and a river in the bottom, indicating that a river eroded the rock over time.
- Examples of simple landforms can include valleys, hills, mountains, plains, and canyons.
- Focus should be on relative time.
- Assessment Boundary
- Specific details of the mechanisms of rock formation or specific rock formations and layers are not expected in state assessment.
