When sand replenishment of a beach is undertaken,

Question

Quizplus · Accepted Answer

It may be important to duplicate the mineralogy and grain size of the original sand. While sand replenishment can help restore the visual appeal of a beach and prevent further erosion, it is important to maintain the natural balance of the beach ecosystem. This includes matching the mineralogy and grain size of the original sand, which can affect the behavior of waves and tides, and impact the habitat of various beach organisms. Therefore, duplicating the natural sand composition is an important factor to consider during the sand replenishment process. The other options are not entirely accurate - sand replenishment may need to be repeated periodically, erosion may still occur even with new sand, and the effort required for sand replenishment can vary depending on the extent of the erosion and the amount of sand needed.
