   What are Earth's layers, from most dense to least dense? Flexi Says: When Earth was entirely molten, gravity drew denser elements to the center and lighter elements rose to the surface. The separation of Earth into layers based on density is known as differentiation.

   How is the Earth divided based on chemical composition and physical characteristics?

   • In general, the Earth can be divided into layers based on chemical composition and physical characteristics. Figure 2.2.1 2.2. 1: The layers of the Earth. Physical layers include the lithosphere and asthenosphere; chemical layers are crust, mantle, and core. Certainly, the earth is composed of countless combinations of elements.

   What are earth's layers based on chemical composition?

   • The following is a summary of the Earth’s layers based on chemical composition (or the chemical makeup of the layers). Earth has three main geological layers based on chemical composition – crust, mantle, and core. The outermost layer is the crust and is composed of mostly silicon, oxygen, aluminum, iron, and magnesium.

   What are physical and chemical layers of the Earth?

   • Physical layers include the lithosphere and asthenosphere; chemical layers are crust, mantle, and core. Certainly, the earth is composed of countless combinations of elements. Regardless of what elements are involved two major factors—temperature and pressure—are responsible for creating three distinct chemical layers.

   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.

   What is the separation of Earth into layers based on density?

   • The separation of Earth into layers based on density is known as differentiation. The densest material moved to the center to create the planet’s dense metallic core. Materials that are intermediate in density became part of the mantle. Lighter materials accumulated at the surface of the mantle to become the earliest crust. Was this helpful?
