Activity #1. Compare and Contrast. Similarities and differences of Venus, Earth and Mars. Do this on a separate sheet of paper. 1. Compare and contrast the three (3) terrestrial planets using table 1. 2. Provide explanations for your observations using table 2. 3. Answer the following guide questions. Guide questions: 1. Does planet size affect gravity? 2. Why do you think Venus has the highest mean temperature among the three planets? 3. Is presence of water a primary factor for a planet to sustain life? Why or why not? 4. Based on your observations using table 2, what are the notable features that makes the earth the only habitable planet among the three terrestrial planets? 5. What conclusions can you make?
