The interior of the Earth is composed of several layers, each with distinct characteristics and properties. These layers can be broadly categorized into the crust, mantle, and core. 1. Crust: The Earth's crust is the outermost layer and is relatively thin compared to the other layers. It is composed mainly of solid rock and is divided into two types: continental crust and oceanic crust. The continental crust is thicker and less dense than the oceanic crust. It primarily consists of granitic rocks. The oceanic crust is thinner and denser, mainly composed of basaltic rocks. The crust is the layer on which we live and where most geological processes, such as earthquakes and volcanic activity, occur. 2. Mantle: The mantle lies beneath the crust and extends to a depth of about 2,900 kilometers (1,800 miles). It is the largest layer of the Earth and constitutes a significant portion of its volume. The mantle is primarily composed of solid rock but can behave like a viscous fluid over lon...
