Estimating the number of specks of sand on Earth is challenging, but scientists suggest there are approximately 7.5 quintillion grains of sand (7.5 x 10^18). This estimate takes into account the vast expanses of deserts, beaches, and ocean floors. However, it's important to note that this number is a rough approximation and can vary significantly based on factors like erosion and sediment deposition.
