Earth's Core. There is more to the Earth than what we can see on the surface. Understanding the basic structure of earth is very important to learn higher concepts well. Earths interior is divided into three main sections. Let’s start from the outside and move our way in. Scientists know that the core is metal for a few reasons. The diagram represents a model of Earth’s surface and internal structure. A slippery layer beneath Earth stops chunks of crust in their tracks, creating "stagnant slabs" in the middle of the mantle.

Moonquakes of very low energy are caused by land tides produced by the pull of Earth's gravity, and, from analysis of moonquake data, scientists believe the Moon has two layers: a crust, from the surface to 65 kilometers depth, and an inner, more dense mantle from the crust to the center at 3,700 kilometers. Lithosphere. The crust is the outer layer of the Earth and it is made of rigid rocks. Some depths below Earth’s surface are shown. In this article (geography section), we discuss the interior of the earth.
