*The Earth's interior is composed of four layers, three solid and one liquid not magma but molten metal, nearly as hot as the surface of the sun.*The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt.*Above the inner core there is an outer core, a shell of liquid iron.

*Earth is home to spectacular and frightening sights and experiences that hint at what is happening deep within the planet.* Volcanoes and earthquakes are powerful evidence of the tectonic plates that grind against one another and the magma that rises through an inner layer.*Scientists gather information about Earth’s interior by recording, imaging, and measuring vibrations, or seismic waves, caused by earthquakes or explosions.
