According to a study published in Scientific Reports, anomalies deep within the Earth's mantle appear to be remnants of submerged tectonic plates—but located far from where such plates are ...

Long-lost remnants of tectonic plates have been discovered sunken deep inside the Earth's mantle. These plate remains were found lurking underneath the center of other continental plates ...

The plates make up Earth's outer shell, called the lithosphere. (This includes the crust and uppermost part of the mantle.) Churning currents in the molten rocks below propel them along like a ...

The Earth has a layered structure made up of the core, the mantle and the crust ... In this diagram, the red lines represent the edges of the tectonic plates that make up the Earth's crust.
