Question

how did the invention of hydraulic mining allow for larger mining operations? (1 point) air blown at high pressure could remove unwanted materials from steel water released at high pressure could move large rocks out of the way. new tools were better able to cut through shallow grass and rocks in the soil. wind power could be used to pump water and produce electricity

Explanation:

Hydraulic mining uses high - pressure water. The key is to analyze each option:

• Option 1: Hydraulic mining uses water, not air.
• Option 2: High - pressure water in hydraulic mining can move large rocks, which is relevant to larger mining operations.
• Option 3: Hydraulic mining is about water force, not new tools for cutting grass.
• Option 4: Hydraulic mining is not about wind power for pumping water and electricity.

Answer:

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