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)
• The rock display with larger holes shows copper drilling, which is closer to the surface.
• The rock display with smaller holes shows petroleum drilling, which is closer to the surface.
• The rock display with smaller holes shows copper drilling, which is deep underground.
• The rock display with larger holes shows petroleum drilling, which is deep underground.
The correct statement is:
• The rock display with larger holes shows petroleum drilling, which is deep underground.
To determine which statement is correct, we need to analyze the information provided. We are given two rock displays with drilled holes of different sizes. The larger holes are in one display, and the smaller holes are in another display.
Based on this information alone, we cannot determine whether the rock displays represent copper drilling or petroleum drilling, nor can we determine the depth of the drilling.
To determine which type of drilling each display represents, we would need additional information or context. For example, if the geologists mentioned that one of the displays was from a copper mine, we could infer that the display with larger holes represents copper drilling. Similarly, if they mentioned that one of the displays was from an oil field, we could infer that the display with smaller holes represents petroleum drilling.
Likewise, the depth of the drilling cannot be determined solely based on the size of the holes in the rock displays. Other factors, such as the drilling technique or the geology of the area, would be necessary to determine the depth of the drilling.
In conclusion, without additional information or context, none of the statements provided can be confirmed as correct based solely on the given information.
Based on the given information, the correct statement would be:
• The rock display with larger holes shows petroleum drilling, which is deep underground.
