Moncks Corner’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 120 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Waccamaw Formation (limestone, sand), from the Pleistocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, sand. Age: Pleistocene, less than 2.6 million years old. About 11 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 6 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Sand, limestone. Age: Tertiary, 2.6 to 66 million years old. About 2 mi of the line.
Peat. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Moncks Corner reaches Charleston Harbor and the Atlantic Ocean by way of the West Branch Cooper and the Cooper: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Moncks Corner; river miles along the main stem, rounded.
Moncks Corner has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 38° in January. About 52 inches of rain fall in a normal year.
On November 14 Moncks Corner normally reaches 69° and falls to 47°. The record high is 76°, in 2007; the record low 26°, in 2013. The most rain on this date, 0.90 in, fell in 1997.
