A collection of earth diagrams are available in the following 101 Diagramss to help you learn about the structures of the earth. The images that we have collected in the following images below show basic layers of the earth. In this educational diagram post about Science learn about the layers of the earth, the crust, the mantle, and the core. First diagram below is the easy and simple version that you can use to teach kids.
The earth diagram above shows the layers of the Earth. The Earth consists of four concentric layers: inner core, outer core, mantle and crust. The inner core is in the center and is the hottest part of the Earth. It is solid and made up of iron and nickel with temperatures of up to 5,500°C. With its immense heat energy, the inner core is like the engine room of the Earth. The outer core is the layer surrounding the inner core. It is a liquid layer, also made up of iron and nickel. It is still extremely hot, with temperatures similar to the inner core. In the following layer diagrams of the Earth, more detailed layers are illustrated.
The mantle is the widest section of the Earth. It has a thickness of approximately 2,900 km. The mantle is made up of semi-molten rock called magma. In the upper parts of the mantle the rock is hard, but lower down the rock is soft and beginning to melt. The crust is the outer layer of the earth. It is a thin layer between 0-60 km thick. The crust is the solid rock layer upon which we live. The crust is made up of tectonic plates, which are in constant motion. Earthquakes and volcanoes are most likely to occur at plate boundaries. There are two different types of crust: continental crust, which carries land, and oceanic crust, which carries water.
