What are landslides mudflows slump and creep examples of?
G3 Test Review
| Question | Answer |
|---|---|
| The process by which natural forces move weathered rock and soil from one place to another is called | Erosion |
| Landslides, mudflows, slump, and creep are all examples of | Mass movement |
| A stream or river that runs into another stream or river is called a | Tributary |
| Mass movement is caused by | Gravity |
What is the most destructive kind of mass movement?
The most destructive type of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Some landslides may contain huge masses of rock, while others may contain only a small amount of rock and soil. A mudflow is the rapid movement of a mixture of water, rock, and soil.
Which of the following is most likely to trigger a mudflow?
Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability. Consequently, the heavy water-laden slope materials (soil, rock, etc.) will succumb to the forces of gravity. Excessive water is thought to be one of the most common triggers for landslides.
What is the difference between mudflow and landslide quizlet?
Both flow rapidly down a slope and can be triggered by an earthquake. Landslides contain only rock and soil, while mudflows contain rock, soil, and a high percentage of water.
Can creep occur on even very gentle slopes?
Creep Creep is the very slow downhill movement of rock and soil. It can even occur on gentle slopes. Creep often results from the freezing and thawing of water in cracked layers of rock beneath the soil. Like the movement of an hour hand on a clock, creep is so slow you can barely notice it.
What is the force that pulls rocks and soil down slopes?
Gravity can pull soil, mud, and rocks down cliffs and hillsides. This type of erosion and deposition is called mass wasting.
What is the fastest form of mass movement?
A rock fall are the fastest of all landslide types and occurs when a rock falls through the air until it comes to rest on the ground—not too complicated.
What is the negative effects of mudflows?
The health hazards associated with landslides and mudflows include: Rapidly moving water and debris that can lead to trauma; Broken electrical, water, gas, and sewage lines that can result in injury or illness; and.
What are the three major agents of erosion?
The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity.
What is the major difference between a landslide and a mudflow?
A landslide is a mass movement of soil, rocks or other debris down a slope or across the surface of the earth. A mudslide is the large-scale movement of fine particles that are partly liquefied down or along a slope.
What is the difference between a mudflow and a landslide?
Landslides occur when masses of rock, earth, or debris move down a slope. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. Mudslides usually start on steep slopes and can be activated by natural disasters.
What are signs of soil creep?
Creep is indicated by curved tree trunks, bent fences or retaining walls, tilted poles or fences, and small soil ripples or ridges.
