The theory of plate tectonics states that the earth's crust is composed of many plates that move gradually across the earth's surface. true or false ?

True  thats why the continents are separate                                                                                 

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!
