Mt. Ararat is an extinct volcano, and there are some signs that it erupted and built up under water. It seems possible that this happened at the time of the Flood, when the continents were below the sea level. At the present time the crust of the earth is depressed in areas occupied by the northern and southern ice caps, as is learned by tracking artificial satellites. The weight of the two ice caps, it is suggested, would cause excessive internal pressure in the earth; and the ocean floors being thinner than the continents, would rupture and then be uplifted. Displaced ocean water, added to the loads of ice, would cause the continents to sink, further uplifting the ocean floors. Magma from the rifts would heat the oceans, gradually melting the ice caps. Then, when the load of ice was mostly gone, equilibrium was restored.
