Geologists trying to drill into the mantle would MOST LIKELY drill from a platform in the ocean, rather than on land, because the crust beneath the ocean is thinner.

Explanation:

The earth's crust is one of the three main layers of the earth and it makes up almost the entire solid composition of the planet, that is, the portion of the earth where the rocks are. Below it is the cloak, which is basically magma. In terms of location, the earth's crust can be divided into two parts: the oceanic crust and the continental crust. The ocean is the thinnest, with a depth ranging from 5 to 10 kilometers, while the continental is thicker, ranging from 30 to 70 kilometers. For this reason, we can conclude that geologists trying to pierce the mantle would probably drill from a platform in the ocean rather than on land, because the crust under the ocean is thinner.
