Discontinuities Inside the Earth refer to the sudden changes in the physical properties of the Earth's interior, such as seismic velocity, density, and composition. These discontinuities are typically observed a

Like all terrestrial planets, the Earth's interior is differentiated. This means that its internal structure consists of layers, arranged like the skin of an onion. Peel back one, and you find another, distinguished from the last by its chemical and geological properties, as well as vast diffe...
Earth’s Interior Layers of the Earth How much do you know about your planet? Text Book page numbers 80 - 87 True or False The Earth is made up of 3 layers. Answer: False 4 Layers The Crust is the thickest layer. The Inner Core is solid. Answer: False Mantle Answer: True The Mant...
(7200 - 9032 oF) Since it is so hot, the outer core is liquid The density of the outer core is between the 10g/cm3 and 12.3g/cm3 Outer core and inner core together cause the earths magnetism Earth’s rotation Outer core rotates while inner core does not and this causes the magnetism...
Earth's interior is gradually cooling over time. As it cools, the liquid outer core crystallizes and becomes part of the solid inner core. Remarkably, the inner core "grows" by about 0.039 inches (one millimeter) every year, which equates to the solidification of 8,820 tons (8,000 tonnes...
Which layer of the Earth has the greatest temperature, pressure, and density? Core Summary The earth is layered with a lithosphere (crust and uppermost mantle), convecting mantle, and a dense metallic core. Pressure, temperature, and density increases as depth increases. http://www.learner.org...
