Soil compaction results from . a. the reduction or elimination of pore space in soil b. the weight of heavy machinery on soil c. livestock walking over soil d. all of the above

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
