How many layers does the earth have and what are they?

Answer 1

3 main layers, crust (lithosphere), mantle and core

^ although that is technically mostly correct, The Mantle is divided into 3 sections. the lithosphere is one of them.. and it includes the crust AND the tough top part of the mantle. The Lithosphere, which contains the tectonic plates (what causes pangea, continental drift, sea floor spreading, earthquakes, volcanoes, tsunamis, etc) 'floats' on top of the Asthenosphere which is the "middle" part of the mantle, and has a dense, 'plastic' kind of melted rock. The flow is very slow there, due to the density caused by the extreme pressure the 3rd one I'm not sure what its called. but i do know it includes the outer core as well extremely as the "bottom" mantel. then there is the inner core where is mostly hot metals at hot temperatures. oh wait i found out the last layer. In total there are 5 layers!!! look

READ THIS: "The structure of Earth can be defined in two ways: by mechanical properties such as rheology, or chemically. Mechanically, it can be divided into lithosphere, mesosphere-mantle, outer-core-1, and the inner-core. The interior of the earth is divided into 5 important layers. Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core.

Answer 2

The Earth has four main layers: the crust, mantle, outer core, and inner core. The crust is the outermost layer, followed by the mantle, which is mostly solid rock. The outer core is a liquid layer made of iron and nickel, while the inner core is a solid ball of iron and nickel at the center of the Earth.
