   • Crust. The earth’s crust is the planet’s outermost layer. It contains all biological life as yet known, yet it is the shallowest layer of all. Some scientists compare the earth’s crust to the top crust on an apple pie – delicate, thin, and covering a piping hot interior.
   • Mantle. The mantle is the second chemical layer of the earth. It is composed of mostly melted rocks, depending on where you are in the depth of the earth.
   • Liquid Outer Core. The core of the earth is composed mainly of nickel and iron, which originated from meteor strikes when the world was first forming.
   • Solid Inner Core. The solid inner core of the earth is about 70% of the size of the moon. Its radius, the distance from its center to its outer edge, is estimated to be about 759 miles.

   What are the layers of the Earth?

   • Let’s get started. Before diving into a discussion about the earth’s layers, there are some things you need to know. First, the earth’s layers are divided into three main parts: crust, mantle, and core. These layers are considered the ‘chemical layers’ because they are identified based on their chemical composition.

   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.
