Why is the population density of the andes and the pampas unevenly distributed? a. because people don't want to live where there is no access to the ocean. b. because the land closest to the ocean is uninhabitable. c. because of the variety of climate and landforms in the region. d. because of the uneven distribution of mineral resources.

The answer is C: Because of the variety of climate and landforms of the region. There is extreme variety in this region, both topographically (wide-ranging altitudes, environments, etc) and in terms of climate. This affects the distribution of the region's population density because different areas are better suited than others to host high populations.
