Question

Which statement accurately compares the environmental impact of underground mining and hydraulic fracturing?(1 point)

Both can impact marine wildlife.

Both can cause earthquakes.

Both involve digging deep into the earth.

Both can cause sinkholes.

Answer 1

Both can cause earthquakes.

Underground mining can trigger seismic events and collapses as rock is removed and stress is redistributed; hydraulic fracturing and related wastewater injection can induce small earthquakes by changing subsurface pressures and reactivating faults.
