The “C60” type of this material induces 60 pounds per square foot of lateral pressure per foot of depth. Values greater than six percent for a quantity abbreviated “COLE” indicate that this material can cause structural damage due to high shrink-swell capacity. The wet thread and shear vane tests measure this material’s strength. Hans Jenny developed a five-factor model for the formation of this substance that includes the mnemonic “CLORPT.” Organic matter (20[1])is most concentrated in this substance’s (20[1])(*) O horizon. This substance (10[1])undergoes liquefaction under stress from earthquakes, and is prepared for use via tilling. (0[1])For 10 points, name this material described by a “texture triangle” whose corners are silt, sand, and clay. ■END■ (10[1])
