When europeans first came to the new world they would typically sail south and west to canary islands, then sail west to get to the west indies and spanish main. on their return, however, they would go north to the "leeward islands" of the caribbean, to the bahamas, bermuda, etc. why did they take this odd route rather than sail straight?

Isay b but i'm not sure. 

In financial aspects, a depression is a sustained, long haul downturn in monetary movement in one or more economies. it is a more extreme monetary downturn than a recession, which is a slowdown in financial action through the span of a typical business cycle. a depression is an irregular and extreme type of recession. so depression is always followed by recession but it is not correct to state that a depression always follow a recession.
