WebStructure of Earth’s Crust The fundamental unifying principle of geology and the rock cycle is the theory of Plate Tectonics. Plate tectonics describes how the layers of the Earth … WebStructure of the Earth Background. Earth is roughly a spherical shape, with the average radius being around 4,000 miles. It is made up of different layers: inner core, outer core, mantle, crust, and atmosphere. About 70% of the Earth’s surface is covered in water, having an average depth of 2.5 miles thanks to rivers and ponds.

The structure of Earth can be defined in two ways: by mechanical properties such as rheology, or chemically. Mechanically, it can be divided into lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core.
