Unformatted text preview: GEO 1013 Third Planet Ch 3 - Weathering & Mass Wasting Types of landslides Flows particles move independent of each other Creep slow movement, often of unconsolidated sediment (soil creep) Debris flow more than the particles larger than sand sized, speed varies Earth/mud flow movement of fine-grained particles and water Types of landslides Slide material moves as a coherent mass Slump downward slipping of Earth materials, usually involves a rotation on concave surface Rockslide generally rapid movement of detached bedrock Fall material free falls Very steep slopes, cliffs FLOWS During creep, the land surface moves more rapidly than deeper layers, so objects embedded in rock or soil tilt downhill. If a hillside creeps as a tree grows, the tree develops pistol butt. SLIDES In slump, blocks of soil or rock remain intact as they move downslope. Trees tilt back into the hillside on this slump along the Quesnell River, British Columbia.Trees tilt back into the hillside on this slump along the Quesnell River, British Columbia....
