How Earth’s mantle is like a Jackson Pollock painting

Bermuda has a unique volcanic past. About 30 million years ago, a disturbance in the mantle’s transition zone supplied the magma to form the now-dormant volcanic foundation on which the island sits.

From Earth’s deep mantle, scientists find a new way volcanoes form

The largest delta plain in Earth’s history

Over the last 540 million years, as the Earth's tectonic plates have shifted, MIT researchers have found that periods of major tectonic activity (orange lines) in the tropics (green belt) were likely triggers for ice ages during those same periods.

Taking a soil core from underwater soil is a bit trickier than soil that's on the surface. Scientists have to utilize boats and plunge the sampling equipment through water and down into the soil.
