Question

the new madrid earthquakes are apparently related to an old buried ______. options: salt mine, rift zone, subduction zone, hazardous waste dump.

Explanation:

The New Madrid earthquakes are associated with a buried rift zone. A rift zone is a region where the Earth's crust is pulling apart, and the New Madrid seismic zone is linked to an ancient rift system. Salt mines, subduction zones (which are more related to plate boundaries with one plate going under another, not typical of the New Madrid area), and hazardous waste dumps are not geologically linked to these earthquakes in the same way.

Answer:

B. rift zone
