Which factor influences the mass movement of particles? O wind blowing across a body of water

O addition of vegetation to a slope

O large rocks and debris on a slope

O puddle of water resting on flat land

large rocks and debris on a slope

Explanation: Mass movement can simply be explained as the flow of earth materials down a slope. Movement of these materials such as rock particles , debris and soils are aid by the steepness of the slope or topography, wind or water moving down a slope at high speed and gravitational influence causing these particles to move down slope in the form of creep, landslide, slump or mudflow. When the slopes are covered with large rocks and debris, the occurrence of mass movement becomes imminent as these particles becomes unstable at slopes. Other influencing factor may include the movement of heavy wind or water down a slope or hill.
