Answer:
Here is a claim-evidence-reasoning (CER) model for the student's claim about the flooding of the Scablands:
Claim: The flooding of the Scablands is due to erosion and melting of glaciers which increased the amount of water until it overwhelmed the dams.
Evidence:
Erosion patterns in the Scablands that suggest a large amount of water was present in the region.
The presence of glacial deposits in the area.
The location of the Scablands near glacial formations that would have melted and contributed to the increase in water.
Reasoning: The evidence supports the idea that melting glaciers and erosion caused a significant increase in water in the region, which then overwhelmed the dams and caused flooding in the Scablands. The presence of glacial deposits and the proximity to active glacial formations suggest that a large amount of water was released into the area, causing the observed erosion patterns and the flooding.
