Lesson 1 Earth’s Layers: We learned to identify Earth’s compositional and physical layers and describe their properties. We identified Earth’s five physical layers: lithosphere, asthenosphere, mesosphere, outer core, and the inner core. Then we looked at the composition of the three layers: crust, mantle, and core. The crust is made mostly of oxygen, silicon, and aluminum which form silicates such as quartz.
