   Dec 15, 2020 · Below the mantle lies the layer known as the Outer Core. This is a thick layer - some 2,200 km (1367 miles) thick - that consists of liquid iron and nickel. In order for the nickel and iron to be in liquid form, the core must sustain intensely high heat.

   • 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.

   Are there 8 layers of Earth?

   • No, there are not eight layers of the Earth. Earth is made up of four distinct layers: the inner core, the outer core, the mantle, and the crust. The inner core is the deepest layer and has a solid inner core and a liquid outer core with a temperature range of 4400 °C to 6100 °C (7,952 °F to 11,012 °F).

   What is the inner core of Earth made up of?

   • The outer core is a liquid layer of molten iron-nickel alloy that generates the Earth’s magnetic field. Finally, the inner core is a solid layer made up primarily of iron and nickel. These layers have distinct chemical compositions and physical states that impact life on Earth’s surface.

   What are earth's layers made of?

   • As research into Earth’s layers reveals more about their composition and behavior, our knowledge of Earth’s history and future continues to grow. The core is composed primarily of iron alloyed with nickel and is the hottest layer of the Earth. The core, Earth’s innermost layer, is divided into two components: the outer and inner core.

   What is the thickest layer 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. Pressure: The pressure of the inner core at the Earth’s center is extreme.

   What is the hottest layer of Earth?

   • The core is composed primarily of iron alloyed with nickel and is the hottest layer of the Earth. The core, Earth’s innermost layer, is divided into two components: the outer and inner core. The solid inner core, predominantly composed of iron alloyed with nickel, has an estimated temperature of 5,700 K (5,400 °C, 9,800 °F).

   The outermost layer, which is where we live, is called the crust. Underneath that is the mantle, followed by the outer core, with the innermost layer called, appropriately, the inner core. Layer 1: The crust.
