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. mark for My Articles similar articles

Super-Rotation for Earth's Core A new earthquake study supports the 1996 finding that Earth's inner core is spinning faster than the planet's mantle and crust -- at a rate detectable on human timescales, but about one-third of the rate first suggested. mark for My Articles similar articles

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. mark for My Articles similar articles
