Why are there so many earthquakes in south america?
o
south america's lack of stable infrastructure and good building codes.
o
south america's proximity to two major oceans and the equator,
south america's location atop the nazca and south american plates of the circum-
pacific belt
o
south america's incredible biodiversity lends itself to hazardous conditions.

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!
