What theory dramatically improved geologist's ability to predict where certain ore deposits were formed? Select one:

a. Geosynclines

b. Plate tectonics

c. Quantum mechanics

d. Faulting theory?

Plate tectonics is referred to a geology theory, which explains the movement of earth's lithosphere. This theory suggests that the earth's lithosphere is made up of many plates, and these plates move on each other causing collision of the plates or sometimes separation of the landmasses.

Sometimes, the movements of the plate occur in such a way that the surface of the earth is buried underground. Even in normal circumstance, some of the surface materials buried underground. So, by studying the type of things existed on the surface in past, one can predict the abundance of a specific substance underground.

Hence, the correct answer is option b. - Plate tectonics.
