and fold.In a subduction boundary, one plate slides below the other.The slabs of the Earth’s crust that are thrust down into the mantle create pull, or suction patterns in the hotter ...

Earth’s earliest crust, formed over 4.5 billion years ago, has long been thought to have lacked the complex chemical features ...

A fascinating new study reveals that a massive chunk of Earth’s crust, buried deep beneath the Midwest, is slowly pulling ...

Gaps form, allowing magma to flow up. As it cools, it adds new, igneous rock to the plate. At destructive boundaries, plates slowly collide, with one being subducted below the other. The slabs of ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began.
