Detailed explanation-1: -The surface of the planet, where we live, is called the crust-it’s actually a very thin layer, just 70 kilometres deep at its thickest point. The crust and the lithosphere below (the crust plus the upper mantle) is made of several ‘tectonic plates’.
Detailed explanation-2: -The mantle is the mostly solid bulk of Earth’s interior. The mantle lies between Earth’s dense, super-heated core and its thin outer layer, the crust. The mantle is about 2, 900 kilometers (1, 802 miles) thick, and makes up a whopping 84 percent of Earth’s total volume.
Detailed explanation-3: -No one has ever drilled into the mantle before, but there have been a half dozen serious attempts. Kola well’s derrick in 1980: still the world’s deepest hole. Image credits: Wikipedia. Decades ago, the Russians drilled deeper than anyone has ever gone.
