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: -They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core.
Detailed explanation-3: -Starting from earth’s surface, the six layers are Troposphere, Stratosphere, Mesosphere, Thermosphere, Ionosphere and Exosphere.-Troposphere starts from earth’s surface and extends upwards 8 to 15 kilometres high. This layer is the most dense and our weather is due to this region. Clouds are found in this layer.
Detailed explanation-4: -Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust.
