Layers of the Earth The Earth is made up of three main layers crust, mantle and core. We live on the outer layer of the Earth called the crust. The Earth’s crust is made up of many different rocks. The layer beneath the Earth’s crust is called the mantle. The Earth’s mantle is made of igneous and metamorphic rocks. Earth’s Core The innermost layer of the Earth is called the core. The Earth’s core is made of metal. The Earth’s core is hot enough to melt but the center of the core is packed together so tightly that it remains a solid. The outer section of the Earth’s core however is hot, thick liquid (magma). magma (outer core) crust mantle outer core inner core metals (inner core)
