The mantle is a thick layer of hot rock. At the center of the Earth is the core. The core is divided into two parts: the outer core and the inner core. The Earth's structure is very important for life. The crust provides a solid surface for us to live on. The atmosphere, which ...
The Earth's structure can be divided into several layers The innermost layer is the core, which consists of a solid inner core and a liquid outer core Surrounding the core is the mantle, a thick layer of rock that undergoes slow convection currents The outermost layer is the crust, which ...
Earth refers toconcentric spherical layerssubdividing the Solid earth, i.e., excludingEarth's atmosphereandhydrosphere. It consists of anouter silicate solid crust, a highlyviscous asthenosphereandsolid mantle,a liquid outer corewhose flow generates theEarth's magnetic field, anda solid inner core. ...
The outer core contains liquified iron, nickel, and other metals. Iron is very dense and is gravitationally pulled toward the center of the Earth. (This process generates heat, which will be discussed later in this lesson.) The inner core is almost pure iron, which is solid due to the ...
