First question: The melting ice cap in the Arctic doesn't contribute to sea level rise in the same way that Antarctic melting glaciers do. Explain this using Archimedes' principle. Consider these questions: Compare the buoyant force on a piece of ice partially submerged and floating in water to the buoyant force on it after it melts into water. How does the volume of the water displaced before and after melting compare? How does this affect the overall level of the water? Problems/General Problems: 11, 14, 25, 27, 28, 32, 33, 35, 46, 49, 50, 51, 54, 68, 69 MCAT: 70-73
