QUESTION: Most of Earths ice is found in Antarctica, where permanent ice caps cover approximately 0.5 percent of Earths total surface area and are 3 km thick, on average. Earths oceans cover roughly 71 percent of our planet, to an average depth of 3.6 km. Assuming that water and ice have roughly the same density, estimate by how much sea level would rise if global warming were to cause the Antarctic ice caps to melt. ANSWER: Water level = 3.6 km + (0.5/71) 3 km = 3.621 km, the oceans would rise 0.021 km which is 21 meters. Why 0.5/71?
