for 1920x1080 (16:9): "An ultra-realistic depiction of Earth’s ground showcasing diverse terrains. On a plain white background, present sections of a desert with dry, cracked earth and wind-swept sand; a dense forest floor with rich, dark soil covered in fallen leaves; rocky mountain ground with jagged stones and patches of snow; and coastal gravel beside a stretch of ocean. Each terrain segment should seamlessly blend into the next, with intricate textures, dynamic lighting, and realistic shadows to highlight the details of each surface. Ensure a captivating depth effect, with crisp contrast between textures."
