In earthmoving, which property stays constant?

Explanation:
The main idea is that only an intrinsic property of the material stays unchanged during earthmoving. The weight of individual soil particles is fixed because each grain has a constant mass. In contrast, the total load weight can change—adding or removing water, changing compaction, or varying the volume of material affects the overall weight. Moisture content can rise or fall with weather and conditions, and temperature can vary as well, influencing behavior but not being a fixed property of the particles themselves. So the weight of the soil particles remains constant.
