The first layer beneath the Earth's crust is called the mantle. The mantle extends to a depth of about 2,900 kilometers (1,800 miles) and is composed of semi-solid rock that can flow slowly over geological time. It is divided into the upper mantle and the lower mantle, with the upper mantle being more rigid and the lower mantle exhibiting more fluid-like behavior.
