What theory dramatically improved geologist's ability to predict where certain ore deposits were formed? Select one:
mrs_skeptik [129]

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.

<span>Normally there are two kinds of roots and they are taproot and fibrous roots. In case of taproots the main root goes downwards and smaller roots branches out of it. In case of taproots, it is true that the spread of roots is smaller than the depth of the roots. In case of fibrous roots, the spread of roots is greater than that of the depth of the roots. A wig tree is an example of a plant having taproot. in the wig tree the root can go to a depth of around 120 meters.<span>
