What Is Under Earth's Surface?

Earth's interior is made of several layers. ... And between the outer core

outer core
Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface. ... Unlike the inner (or solid) core, the outer core is liquid.

and the crust is the mantle, which, at around 2,900 kilometres thick, accounts for the bulk (around 84 per cent by volume) of the planet. Carrying Earth's internal heat to the surface, the convecting mantle creeps like tar on a hot day.

What is beneath the Earth's surface?

The mantle is about 1,800 miles (2,900 kilometers) thick and appears to be divided into two layers: the upper mantle and the lower mantle. The boundary between the two lies about 465 miles (750 kilometers) beneath the Earth's surface. The crust is the outermost layer of the Earth.
