Layers

The Crust makes up only one percent of the earth's mass.

The Mantle The mantle is a layer between the crust and the outer core.

Outer Core outer core of the Earth is a liquid layer about 2,260 km thick composed of iron and nickel which lies above the Earth's solid inner core and below its mantle.

Inner Core At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles.

Solid or liquid

Each of these layers can be further divided into two parts: the inner core and outer core and the upper and lower mantle and the crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel. The inner core is solid, while the outer core is liquid.

Structure/Mass

The interior structure of the Earth is layered in spherical shells, like an onion.

The structure of Earth can be defined in two ways: by mechanical properties like rheology (rheolgy is the branch of physics that deals with Deformination and flow matter) or chemically. Mechanically, it can be divided into lithosphere, asthenosphere (the upper layer of the earth's mantle) , outer core, and the inner core. Chemically the Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core. The geologic component layers of Earth[3] are at the following depths below the surface:

The distance to the center of the Earth is 6,371 kilometers (3,958 mi), the crust is 35 kilometers (21 mi) thick, the mantle is 2855km (1774 mi) thick — and get this: the deepest we have ever drilled is the Kola Superdeep Borehole, which is just 12km deep.

Temperature

about 61 degrees F

The average temperature on Earth is about 61 degrees F (16 C). But temperatures vary greatly around the world depending on the time of year. Summers tend to be warmer and winters colder. Also, temperatures tend to be higher near the equator and lower near the poles.

Facts about the earth

Did you know the earth is the third planet from the Sun And the sun is the densest planet in the Solar System.

Also the mantle is the thickest layer of the earth and it is a solid
