   Layer 2: The mantle. Moving inward from the crust to the next layer, called the mantle, reveals a second layer of Earth with markedly different properties. The mantle layer comprises approximately 84% (!) of the Earth’s volume and 67% of its mass, which means that it is both the largest and heaviest of the four layers.

   • 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 is the upper layer of Earth called?

   • Asthenosphere: This is the upper part of the mantle marked at 1300c isotherm, containing highly viscous ductile material. Mesosphere: This layer lies under the above two layers of Earth: the Lithosphere and the Asthenosphere. However, it is still above the outer core and refers to the mantle.

   What are the layers of the Earth composed of?

   • In terms of composition, the crust is mostly silicate rocks and oxygen, while the core is largely iron and nickel. The mantle, which comprises the majority of Earth’s volume, is predominantly composed of silicate minerals rich in iron and magnesium. Now, let’s explore ten interesting facts about the layers of the Earth:
