The three layers of the earth, in order from outside to inside, are the crust, the mantle and the core. The mantle is the thickest and most massive layer, while the core has the highest temperatures of anywhere in the planet.
The crust ranges between 37 and 50 kilometers in thickness, and makes up only one percent of the earth's total mass. It is made up of primarily aluminosilicates. The mantle is made up dense, semi-solid rock that is composed of magnesium silicates. It is about 2,900 kilometers thick. The core, which is part solid and part liquid, is mostly iron, and creates the magnetic field for the planet.Learn More
The crust and upper mantle of the Earth form the lithosphere. The lithosphere is about 62 miles thick. The part of the lithosphere that supports the continents is thicker than the part of the lithosphere that supports the oceans.Full Answer >
A break in the Earth's crust is called a fault. According to Dictionary.com, a fault in geology is a fracture in the Earth's crust that results in the displacement and loss of continuity of rocks on either side of the fracture plane. A fault is the result of plate-tectonic forces.Full Answer >
The Department of Earth and Ocean Sciences at the University of British Columbia defines geology as the study of the Earth and its composition, which includes the crust. A geologist covers everything from studying the times when dinosaurs roamed the Earth to predicting modern day earthquakes.Full Answer >
The distance between the Earth's crust to the Earth's core is approximately 3,958 miles. Of this distance, the crust only makes up approximately 21 miles. Between the crust and the outer core is the mantle, which spans a distance of 1,774 miles.Full Answer >
