If we could green the Sahara, would it be able to sustain itself?
Earth ScienceAsked by: Erin Colon What would happen if the Sahara was green? Stager’s research suggests that as the Sahara turns green, it could trigger a warming trend out to sea in the Atlantic Ocean that would make our weather here in the eastern US far more volatile. “When you green the Sahara, there’s less dust,

If I could drill a hole into the mantle, would it form a volcano?
Earth ScienceAsked by: Carlos Feliciano Drilling into the center of the Earth would have no effect on volcanos, which do not have a direct conduit to the molten core, as his diagram falsely suggested. Volcanic material comes from reservoirs no deeper than 30 miles underground. The core begins about 1,800 miles beneath the surface. Is it
