GEOLOGY

Detailed explanation-1: -Have you ever thought about what it takes to drill to the centre of the Earth? If you think it sounds difficult, you’re right! Not only has no one ever drilled to the centre of the Earth, no one has ever even managed to drill through the Earth’s crust.

Detailed explanation-2: -Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Detailed explanation-3: -You would need a super-powered drill to get through rock and metal within Earth’s three layers. First, there’s the Earth’s crust. It’s the thinnest of three main layers, yet humans have never drilled all the way through it. Then, the mantle makes up a whopping 84% of the planet’s volume.

Detailed explanation-4: -The layers of the Earth-the Moho is the boundary between the thin veneer of crust and the mantle. Back to Project Mohole! Its goal was to drill until we could directly sample the mantle-that is, drill through the oceanic crust, through the Moho and into the uppermost mantle.
