  "caption": "A bulldozer moves forward across a construction site, its blade pushing and compacting loose brown soil into a rising mound. The terrain is uneven, marked by tire tracks and scattered rocks, with concrete curbs lining the perimeter. In the background, a yellow excavator sits idle near a building under construction. As the dozer advances, soil clumps shift and settle under pressure, demonstrating friction and gravity's influence on granular material.",
