Why do many islands in the south pacific lack an adequate standard of living?

a)the islands do not have any natural resources.

b)the islands are too small to provide sufficient natural resources.

c)constant warfare has weakened the economies of the islands.

d)the climate is too harsh on the islands to properly support human life.

The options c) and d) are not true (although d can be partially argued for: they have problems with soil erosion and winds).

a and b however are both true- and they are connected to each other, a being the result of b.

Becasue of this, I think that B is the best option, as they have some but not many natural resources- due to their size.

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!
