Deep Earth May Hold an Ocean Earth's deep interior, more than 1,000 kilometers below the surface in the mantle, could prove to be a watery place. That's the conclusion researchers drew from an anomaly uncovered by the first global map of Earth's lower mantle, using a new type of seismic analysis. |

Earth's Core is Solid, After All Seismic waves passing through Earth's center have long puzzled researchers, as some waves travel fast enough to indicate that Earth's inner core is solid iron-nickel crystals, but they do not travel quite as quickly as scientists would expect, based on studies of stiff iron alloys. |
