Convection currents in the mantle cause seafloor spreading. What is the result of this plate movement? magma piles up on top of the plates involved

the plates involved are cracked on the surface

earthquakes occur along the edge of the larger plate

the plates move apart, causing the ocean floor to increase in size

Iknow what you are working on the correct answer is c

The answer i think is d

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!
