Fritdjof Nansen's FRAM expedition was iced-locked in the Antarctic ocean. A useful scientific hypothesis is one that has been proved. 4.The scientific method is an infallible way to obtain knowledge and understand nature. Regions near the oceans have more dramatic seasonal changes in temperature than regions in the middle of continents. The average depth of the ocean is greater than the average height of land mountains.
Trenches are the longest continuous structural features of the deep-ocean basins.
For a given mass of water, more heat is needed to melt the water than to vaporize it. The Atlantic ocean is becoming larger whereas the Pacific ocean is shrinking. The Hawaiian islands were formed in the same way as Japan and the Philippines. Because of isostatic balance, the asthenopshere floats on the lithosphere. Relict sediment is commonly found on the continental shelf.
