Detailed explanation-1: -Earth consists of three main layers: the crust, the mantle, and the core (Figure 3.4). The core accounts for almost half of Earth’s radius, but it amounts to only 16.1% of Earth’s volume. Most of Earth’s volume (82.5%) is its mantle, and only a small fraction (1.4%) is its crust.
Detailed explanation-2: -The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core.
Detailed explanation-3: -Crust: the outer layer of rock on which humans and animals live and plants grow. Mantle: a semi-solid magma layer consisting of iron, magnesium, and silicon. Core: centrally located solid mass of metal (inner core) and a liquid mass of iron and nickel (outer core).
Detailed explanation-4: -The core is made of two layers: the outer core, which borders the mantle, and the inner core. The boundary separating these regions is called the Bullen discontinuity.
Detailed explanation-5: -The earth is made up of three different layers: the crust, the mantle and the core.
