A temporary long, narrow excavation that will eventually be filled in is called?

• A. Draglines
• B. Riprap
• C. Trench
• D. Plasticity index

Answer: (C)

A trench is the long, narrow excavation that is dug for a specific purpose and then backfilled later. This shape—long and narrower than it is wide—and the plan to fill it back in fits the common definition of a trench, often created to install utilities or run drainage. Draglines are a type of excavating equipment, not the name of the excavation itself. Riprap is rubble used to protect slopes, not an excavation. The plasticity index is a soil property describing how plastic the soil is, not a kind of cut.
