Fine grained igneous rocks that have small grains cooled rapidly and are likely to be

They will be basalt. Formed by volcanic activity on the seafloor, thus the water will contribute that the magma is cooled very quickly and make it fine grained. This usually happens where the seafloor is spreading, on the line that separates two tectonic plates. These rocks are extrusive rocks.

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!
