   What are the 3 main layers of Earth?

   • Earth consists of three main layers: the crust, the mantle, and the core (Figure 3.3). 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. Figure 3.3 Earth’s interior.

   What is the outermost layer of the Earth composed of?

   • The outermost layer is the crust and is composed of mostly silicon, oxygen, aluminum, iron, and magnesium. There are two types of crust, continental and oceanic crust. Continental crust is about 50 kilometers (30 miles) thick, represents most of the continents, and is composed of low-density igneous and sedimentary rocks.

   Why is the Earth's outermost layer rocky and rigid?

   • The Earth’s outermost layer—its crust —is rocky and rigid. There are two kinds of crust: continental crust, and ocean crust. Continental crust is thicker, and predominantly felsic in composition, meaning that it contains minerals that are richer in silica. The composition is important because it makes continental crust less dense than ocean crust.

   What are some interesting facts about the layers of the Earth?

   • Now, let’s explore ten interesting facts about the layers of the Earth: Thickest Layer: The mantle is the thickest layer of the Earth, accounting for about 84% of the Earth’s volume. It extends approximately 2,900 kilometers beneath the crust, which makes it nearly twice the thickness of the Earth’s outer and inner cores combined.
