Feb 2, 2023 · The earth’s internal structure is made up of three major layers: the crust, the mantle, and the core, The mantle and the core are further subdivided to form five distinct layers in total.
Jan 23, 2020 · Above the core is the mantle. Like the core, the mantle also has two layers. These are the lower mantle and the upper mantle. Both layers of the mantle are made up of hot, dense, semi-solid rock.
Aug 1, 2023 · The four primary layers are the crust, the mantle, the outer core, and the inner core. However, geologists subdivide these layers into a complex structure that better describes the Earth’s intricate composition and behavior.
- 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.
Aug 8, 2023 · 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).

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.
