Soil Formation Sequence Answer Key

This worksheet focuses on sequencing the steps that transform rock into soil. Students read a scrambled list of events (A-H) describing processes such as cooling, cracking, root growth, erosion, breakdown into grains, organic mixing, and soil layer buildup. They must place the events in correct chronological order by writing letters in sequence. This helps learners understand that soil formation is gradual and depends on both weathering and erosion. Students practice recognizing cause-and-effect relationships among Earth processes. The challenge question asks students to explain why weathering and erosion are both necessary, strengthening scientific explanation skills. Overall, the worksheet builds a clear mental model of how soil develops over time.
