The earth is a dynamic planet because it is constantly undergoing changes inside and outside. It is made up of rocks. The earth is made up of several concentric layers with one inside another. There are three types of layer- crust, mantle and core. The Crust is the uppermost layer over the earth’s surface which is about 35 km on the continental masses and only 5 km on the ocean floors. Continental mass is constituents of silica and alumina constituents, thus it is called sial. The oceanic crust mainly consists of silica and magnesium; it is therefore called sima (si-silica and ma-magnesium). Mantle is just beneath the crust which is extends up to a depth of 2900 km. below the crust .The innermost layer is the core with a radius of about 3500 km. It is mainly made up of nickel and iron and is called nife (ni – nickel and fe – ferrous i.e. iron).
