Distance from surface Earth to the true center of the Earth nearly four thousand miles. To reach it, you must dig into the four layers of this planet. These layers are the crust, mantle, outer core and inner core.

Of all these layers, only one is still visible to the naked eye, namely the crust. Like the crust on top of a cake or bread, this layer forms the outermost part of the Earth. The Earth’s crust contains solid rock and minerals, including materials such as coal and precious metals.
How thick is the Earth’s crust? Varies. Beneath the oceans, this layer can be about 3.1 miles (5 kilometers) thin. Beneath the land, it ranges from 18.6 to 43.5 miles (30–70 km) thick.

Regardless, humans have never before drilled into the Earth to break through its crust. The farthest human drilling has ever been is 7.6 miles (12 km).
Beneath the Earth’s crust is Earth’s largest layer, which is called the mantle. This layer extends for 1,865 miles (3,000 km) and is semi-solid. Most of it consists of iron, magnesium, and silicon. The Earth’s mantle is where diamonds form.
Experts believe that melted rock forms the very top of this layer. This allows the Earth’s tectonic plates to move above it.
