What else can I help you with?
What mass wasting factor do you think are of most concern in the portland area?
Landslides due to rainfall, or earthquake that causes soil liquefaction, which would cause widespread landslides/slumps
Compare landslides and slumps?
Landslides and slumps are both types of mass wasting events involving the movement of soil and rock down a slope, but they differ in their characteristics. Landslides typically involve a rapid, chaotic movement of material and can occur in various forms, such as rockslides or debris flows. In contrast, slumps are a specific type of landslide where a cohesive block of material moves downward and rotates along a curved surface, leading to a more distinct and recognizable failure pattern. Both phenomena can be triggered by factors like heavy rainfall, earthquakes, or human activities, but their mechanisms and resulting shapes are what set them apart.
What are four main types of mass movement?
The four main types of mass movement are landslides, rockfalls, mudflows, and slumps. Landslides involve the downslope movement of material along a defined surface, rockfalls occur when rocks break loose and fall rapidly down a slope, mudflows are rapid flows of mud and water mixed with debris, and slumps involve the movement of material along a curved surface.

What is the agent of erosion for mass movement?
Gravity is the main agent of erosion for mass movement. It pulls rock and sediment downslope, causing mass wasting processes like landslides, rockfalls, and slumps.
What are four ways that gravity moves sediment and rock?
Gravity moves sediment and rock through mass wasting events such as landslides, rockfalls, slumps, and creep. These processes involve the downslope movement of material due to the force of gravity, shaping landscapes over time.
What are the different types of mass movement?
55+7
What agent of erosion is mass movement?
Mass movement is an agent of erosion that involves the downhill movement of rock, soil, and debris due to gravity. It includes processes such as landslides, rockfalls, and slumps, which can occur when the force of gravity overcomes the strength of the material holding the slope together, leading to erosion.
What is the thing called when rock and soil fall due to gravity?
The process is called mass wasting or mass movement. It refers to the downslope movement of rock, soil, and debris under the influence of gravity. This can result in various forms such as landslides, rockfalls, and slumps.
How do landslides effect floods?
they are the same because they both have to do with water troubling an area
Which is not a reason why policy makers avoid spikes and slumps in product prices?
The spikes and slumps can inhibit competition among businesses.
What is erosion called mass movement is caused by?
Erosion called mass movement is caused by gravity pulling material downslope. This can include processes like landslides, slumps, and rockfalls where a mass of rock, soil, or debris moves downward due to gravity's force.
