Earth S Interior Layers Diagram
The deepest layer is a solid iron ball about.
Earth s interior layers diagram. The inner earth is composed of three main parts sometimes called the layers of the earth. The earth s internal structure is made up of three major layers. It is the thin relatively outermost layer that wraps around the earth and ranges in.
Trevor nace layers of earth 1. The crust the mantle and the core as shown in the diagram of the earths interior below. Knowledge of earth s interior is derived primarily from analysis of the seismic waves that propagate through earth as a result of earthquakes.
Continental crust igneous metamorphic and sedimentary rocks. Depending on the material they travel through the waves may either speed up slow down bend or even stop if they cannot penetrate the material they encounter. A cut away illustration of earth s interior.
The middle portion of the mantle that is made of hot rock that can flow. The crust the mantle and the core the mantle and the core are further subdivided to form five distinct layers in total. Each of the layers involving the main layers has its own set of characteristics that are described below along with their chemical compositions and.
Contains the crust and the top most part of the mantle. Terms in this set 14 crust. Oceanic crust mostly basalt.
Plate tectonics plate tectonics earth s layers. Earth s crust is what we walk on every day. The earth s interior is composed of four layers three solid and one liquid not magma but molten metal nearly as hot as the surface of the sun.
