WebAug 28, 2024 · Finally, topographic stress, also known as mass movement, is caused by gravity. The gravity drags heavy, loose items down to lower elevations. Effects Of Scree On The Ecosystem . As scree accumulation grows at the bottom of mountains and cliffs, it can affect the ecosystem around it by preventing large plants from taking hold and growing. To examine the conditions where landslides occur, we calculated the maximum, minimum and mean values for stress model proxies and potential controls within each landslide scar zone.
