31. Such a collision from space, Toon predicted, could send tsunami waves 100 yards high sweeping across entire ocean basins . 32. At first, the hot, faulted edge of the continent was high and buoyant relative to the new ocean basin . 33. The range forms the watershed between the Arctic Ocean ( via Lake Baikal ) and the Pacific Ocean basins . 34. They are largest on average in the northwest Pacific Ocean basin and smallest in the northeastern Pacific Ocean basin. 35. This has led to the hypothesis that mantle plumes contribute to continental rifting and the formation of ocean basins . 36. A model of present-day mass change due to post-glacial rebound and the reloading of the ocean basins with seawater. 37. More massive exoplanets would tend to have a regular surface gravity, which can mean shallower and more hospitable ocean basins . 38. Such deposits and sediments collect in ocean basins today, replicating the conditions under which oil was formed in the past. 39. They are also credited with providing the first real view of major seafloor features such as the deep ocean basins . 40. Samples of the oceanic crust and uppermost mantle from ocean basins document that ultramafic rocks there commonly contain abundant serpentine.
