The crust is the top layer of the earth. It is the layer that everybody stands on.
The Mantle is mostly solid bulky.Earth's mantle is a silicate rocky shell with a thickness of 2,886 kilometer (1,793 mi).
The Outer Core
The outer core is mostly made out of Nickel and iron and is about 2,300 km (1,400 mi) thick
The inner core
The inner core has been believed to be primarily a solid ball with a radius of about 1,220 kilometers (760 miles),
The Continental Crust
The Continental Crust The continental crust is the layer of granitic, sedimentary and metamorphic rocks, it is less dense than the material of the Earth's mantle and "floats" on top of it.
Oceanic crust is about 6 km (4 miles) thick. It is composed of several layers, not including the overlying sediment.
The lithosphere is the solid outer section of Earth, which includes Earth's crust (the "skin" of rock on the outer layer of planet Earth)
The asthenosphere is the highly viscous, mechanically weak and ductility deforming region of the upper mantle of the Earth.
The Convection Currents in the Mantle
Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma
The Ice Caps on the North and South Poles
A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite ... Earth's North Pole is covered by floating pack ice (sea ice) over the Arctic Ocean.
