Comparison Chart Answer Key

This worksheet requires students to compare Earth’s volcanoes with those on Io or Mars using a structured chart. Learners fill in facts for features such as size, eruption style, materials, frequency of activity, and surface impact. This task develops comparative analysis skills and highlights how volcanic activity differs across planetary environments. Students must draw from both prior knowledge and provided details to complete the chart meaningfully. A reflection prompt encourages them to consider which world’s volcanoes pose the greatest danger, strengthening their understanding of geological forces beyond Earth.
