What type of rock would you expect to form from the material found along a beach? crystalline sedimentary metamorphic igneous?

Sedimentary rock.
“Sedimentary beach stones are formed on shores or in the water by the weathering of older stones. These bits and chips of older stones settle to the ground on layers along with the remains of organic materials, like parts from plants and animals. Through time they harden into compact sediment. Fossil stones found on the beach are this kind of rocks. Other examples of sedimentary rocks and beach pebbles are: sandstone, shale, conglomerates and breccia”

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!
