What is the fundamental difference between “cut” and “fill” in earthmoving?

• A. Cut builds up terrain while fill creates holes.
• B. Cut removes earth to reach the design elevation; fill adds earth to reach it.
• C. Cut means removing water; fill means adding water.
• D. There’s no difference between cut and fill.

Answer: (B)

In earthmoving, the target is the design elevation. Cutting means removing earth from places that are higher than the plan, and filling means adding earth to places that are lower than the plan. So the fundamental difference is removal versus addition to reach the design grade. For example, if a hilltop sits above the design line, you cut it down; if a valley sits below the line, you fill it up. This distinction matters for material balance and cost, since cut material can sometimes be reused as fill or hauled away if there’s more cut than fill. The other options mix up roles or bring in water, which isn’t part of the cut-and-fill concept.
