The earth's interior consists of three main parts: the core at the center, mantle as the middle layer, and crust, like the 'shell.' The closer to the core you are, the hotter it is. There are plenty of websites with information on the earth's interior.
Everything you need to know about how the earth works is available on www.sciencemag.org/content/309/5731/87.full. Essentially, the earth is made up of 3 parts; the crust or shell, the mantle and the core, which is the innermost and hottest part of earth.
