To determine the nature of the differences between northern and southern Arizona, geologists could: map the geology in detail, take seismic profiles, study drill core, and reconstruct the geologic history between each province. True

False

True

Explanation:

The fourth methods outlined in the paragraph are useful to determine the nature of the differences between the geology of northern and southern Arizona.

This is because these geology differences can manifest in seismic profiles, in geologic history (for example, the differences in the rock formations that form the soil of the two regions), in drill core studies, and also, in a detailed map of the geology of the state, where ideally, the results from the previous studies would be mapped.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
