TILTING OF TREE TRUNKS, POLES AND PILING OF SOIL BEHIND A WALL ARE EFFECTS OF

  • A. Mud flow
  • B. Soil creep ✓
  • C. Rock slide
  • D. Land slide

 

The answer to the question is: B. Soil creep

The tilting of tree trunks, poles, and piling of soil behind a wall are effects of soil creep. Soil creep is a slow, gradual mass movement of soil and rock debris downhill due to the force of gravity. It is characterized by the imperceptible downslope movement of soil and regolith, resulting in the gradual tilting of trees, poles, and the piling of soil behind retaining walls.

Soil creep occurs when individual soil particles move downslope under the influence of gravity. This movement is often imperceptible to the naked eye but can be observed over time through the displacement of objects such as tree trunks, poles, and the accumulation of soil behind structures. The process is driven by a combination of factors including expansion and contraction due to freeze-thaw cycles, wetting and drying, and the force exerted by plant roots.

Soil creep can have significant impacts on human infrastructure and natural landscapes. It can lead to the deformation and damage of roads, buildings, and other structures. In natural landscapes, it can contribute to the shaping of landforms over long periods of time.
