Atlantic and the pacific.

Explanation:

The Pacific plate is known as the shrinking plate and is moving at a speed of about 7-11 cm in a year,  in the northwestwards due to the spreading or the opening up of the Atlantic plates due to the mid-oceanic ridge and in the S-shaped patterns of the ocean between western Europe and eastern America.

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!
