“Create a detailed topographic illustration of a diverse landscape that includes a basin landform, a valley, a gully, and an erosion ditch. The basin should appear as a low-lying, bowl-shaped depression surrounded by higher terrain. The valley should be a broad, elongated depression between hills or mountains with a river flowing through it. The gully should be a narrow, steep-sided channel formed by water erosion, and the erosion ditch should be a shallow trench showing signs of recent soil erosion. Use realistic terrain textures and natural colors to highlight each landform clearly.”
