Question

Question 11 of 33 How did the invention of hydraulic mining allow for larger mining operations? A. Air blown at high pressure could remove unwanted materials from steel. B. Water released at high pressure could move large rocks out of the way. C. New tools were better able to cut through shallow grass and rocks in the soil. D. Wind power could be used to pump water and produce electricity.

Answer 1

Water released at high pressure could move large rocks out of the way.

Answer 2

The invention of hydraulic mining allow for larger mining operations because water released at high pressure could move large rocks out of the way.

Answer: Option B

Step-by-step explanation:

Hydraulic mining is the process of using high pressure water jets at rocks to move them, break them and eventually remove them. Water is one among the most important components in this mining process.

This was mainly used so that miners can go deeper when they are mining and can eventually take on more deeper mining missions, especially due to the water which is released at high speed and pressure could move large rocks out of the way.
