Earth is a complex and dynamic planet, with a unique structure that plays a crucial role in shaping our world. From earthquakes and volcanic eruptions to the formation of mountains and oceans, Earth's structure is constantly in motion. This guide will introduce you to the inner workings of our planet and the exciting world of geology. Outer Layer: The Earth's Crust: The Earth's outermost layer is called the crust, and it's the solid surface that we live on. The crust is broken into several large plates that move on the underlying semi-liquid layer, causing earthquakes, volcanic eruptions, and the creation of new land masses. Mantle: Beneath the Earth's crust lies the mantle, a dense, semi-liquid layer that makes up the bulk of the planet's mass. The mantle is divided into two parts: the upper mantle, which is solid and convecting, and the lower mantle, which is fluid and convecting. The movements of the mantle are responsible for the creation of new oceanic cr
