How Sand Shortages Are Changing the World

~60 min · 15 stations

How Sand Shortages Are Changing the World is a self-paced learning path in Earth Sciences & Geography, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify why sand remains critical for modern infrastructure; describe how natural erosion creates different sand types; analyze how urban growth drives massive sand extraction.
