Explainer: Earth — layer by layer - Science News Explores
Nov 11, 2019 · Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person. In fact, the deepest humans have ever drilled is just over 12 kilometers (7.6 miles).
Core

Layers of the Earth - Science Notes and Projects
Aug 1, 2023 · The four main layers of the Earth are the crust, mantle, outer core, and inner core. The Earth, like an onion, consists of several concentric layers, each with its own unique set of properties and characteristics.
Layers of the Earth: Facts, Definition, Composition, & Diagram
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.
Earth's inner core - Wikipedia
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon 's radius.
Internal structure of Earth - Wikipedia
The internal structure of Earth are the layers of the Earth, excluding its atmosphere and hydrosphere. The structure consists of an outer silicate solid crust, a highly viscous asthenosphere, and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core.

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).
5.3: The Composition and Structure of Earth - Geosciences ...
Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal.
