Shades of “The Core”!

Scientists digging to bottom of Earth – LiveScience –
Scientists have been digging at the bottom of the ocean floor near the Mid Atlantic Ridge, in an attempt to reach the Moho, the boundary between the crust of the planet, and the mantle. That boundary is far shallower at the bottom of the ocean than it is on land. (As seen in the Core, the reason why they begin in the ocean)
Very cool indeed. The knowledge about the mantle of the Earth that we could get in coming years as the drilling reaches and pierces the boundary could answer a lot of questions about the Earth’s composition, oceanic crust formation and more.
