Q

Several types of minerals are mined from locations around subducction zones. As subduction occurs, hot magma is pushed upward into the subsurface. The heat of magma causes groundwater to rise and cool. As te groundwater moves, it extracts minerals from the subsurface and deposits them near the surface in veins that flow in all directions. The most efficient way of mining for these minerals is
a open pit mining
b mountaintop removal
c subsurface mining
d strip mining

A

A) open pit mining
