A scientist uses a special instrument to measure the depth of Earth’s crust. He measures one location that is 65 kilometers deep. Where is this section of crust most likely located?

below a vast ocean
below a deep canyon
below a mountain range
below an island volcano

A depth of 65 kilometers is quite significant and is typically found in areas where the Earth's crust is particularly thick. This depth is most likely located below a mountain range. Mountain ranges are often associated with thicker crust due to the processes of tectonic plate collision and uplift. In contrast, oceanic crust is generally thinner, and while volcanic regions can have varied depths, 65 kilometers is more characteristic of continental crust beneath mountain ranges.
