Which of these would most likely be shown on a map of a more developed country’s quaternary economic sector?

I would say “C” Major universities and research institutions, because the Quaternary sector is based on processing and sharing information and is considered the “knowledge based” part of the tertiary sector. Major universities and research institutions require a lot of knowledge based work and have job positions working their such as teachers and researchers. Hope this helps. :)

Humid continental climate is found in the interior of continents between the 30 and 60 degrees latitude, but usually above the 40 degree line.   40 degrees north of the equator means less direct sunlight and therefore less warmth.   this climate is mainly found in the northern hemisphere since there are no major landmasses in the southern hemisphere.  if you live in northern indiana, you know all about humid continental because that is the climate type you have!

Water flows along the east coast and across the western tropical pacific towards south america, while they both are directed towards that way,  el niño does not directly affect the southern flow of water along the coast.
