Explanation:The Earth is composed of four different layers. Many geologists believe that as ... WebEarth 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.
