Eroding Land

⛰️ When it rains, where does the hill's soil go? The light color shows the original hill, and the dark color is the hill now. Change the slope, rain strength, or grass cover to see how erosion changes and how soil piles up at the bottom — soil doesn't disappear, it moves! ⚖️ But if you change two things at once, you won't know what caused the change. Place two hills side by side and change just one variable to learn how scientists do fair tests. 🌱 Finally, protect your hill with grass, stone walls, or terraces! You have a budget, so choose wisely. This app was made with code too · Remix it to build your own hill!
