Soil quality and rainfall increase the rate of tree growth and change the color of soil. soil density makes it harder for large landforms to form but serves as strong foundations for trees. Soil strength makes it easier for landforms to support themselves and also support the weight of trees. Low soil quality and rainfall would make it a desert, low soil strength and density would make it a swamp. If you combine the two, I guess it would be a soft snow cap in the middle of Greenland? Very advanced version of a very simple project upgraded version use turbo mode or else the project will be too slow Made originally by @lol_Scratch_xd Also, the chance of a tree growing on 10 soil quality, 10 rainfall, 16 soil density, and 6 soil strength is 1/100,000
