Which type of region do you feel is more common, homogeneous, nodal, or vernacular? why?

Nodal regions are more common than vernacular and homogeneous regions.

Explanation:

First of all, we need to explain all of the concepts to understand the answer.

Homogeneous region: a homogeneous region is a region defined by its physical and geographical means. It has nothing to do with culture or people. Thus, it is the less common of the three because well the world's geography is amazingly different, we have mountains, rivers, flatlands, etc. So, the option is wrong.

Second, the vernacular region is a type or region in which different sites share something in common like an invention, person of interest or vicinity with a singular place and they identify themselves as the same region. This could be very common, however, the answer is incorrect because there is just not as much as the third option.

Third, Nodal region. The nodal region is the type of region composed by a metropolis and smaller different sites that are interconnected and share focal point to their interactions. This is the most common of all because the structure of civilization is built under this model.

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.
