Plainville’s center stands about 470 ft above sea level. Within three miles the land runs from 450 ft to 520 ft, a difference of 70 ft: gently rolling country. The highest named summit within 15 miles is Sefert Hill, about 700 ft, 9 miles south.
Under the town center the state geologic map shows Raccoon Creek Group (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 3 rock units mapped at the surface.

A raindrop that lands in Plainville reaches the Gulf of America by way of Smothers Creek, the White River, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,260 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Plainville; river miles along the main stem, rounded.
Plainville has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 24° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 48 inches of water.
