Your class goes on a field trip to observe drilling machinery. The geologists at the drill site show you displays of drilled rocks to compare different types of drills and methods. The drilled holes in one rock display are significantly larger than the holes drilled in the display next to it. Given this information, which statement is correct? (1 point)

Answer 1

The correct statement is:

The rock display with larger holes shows petroleum drilling, which is deep underground.

Larger holes are typically associated with methods used for drilling for petroleum, especially when accessing deeper reservoirs, while smaller holes are generally characteristic of drilling for minerals like copper, which may be found at varying depths but usually involves more precise drilling.
