Telephone polls being tilted on a hill are an example of this type of mass movement.
- A.
Slump
- B.
Creep
- C.
Mudflow
- D.
Rock fall
Correct Answer
B. CreepExplanation
Telephone polls being tilted on a hill are an example of creep, a type of mass movement. Creep refers to the slow, gradual movement of soil or rock downhill, caused by the force of gravity. In this case, the tilt of the telephone polls suggests that the ground beneath them is slowly shifting and causing them to lean. Unlike other types of mass movement, such as mudflows or rock falls, creep occurs over a long period of time and is often not easily noticeable.Rate this question:

What type of mass movement would be caused by ice melting on a volcano after an eruption
- A.
Creep
- B.
Slump
- C.
Lahar
- D.
Mudflow
Correct Answer
C. LaharExplanation
After a volcanic eruption, if ice on the volcano melts due to the intense heat, it can lead to the formation of a lahar. A lahar is a type of mass movement that occurs when volcanic material mixes with water, creating a fast-flowing mixture of mud, debris, and water. This mixture can travel down the slopes of the volcano, causing significant damage to the surrounding areas. Therefore, the correct answer in this case is lahar.Rate this question:

Bug chunks of land falling down a curved slope all at once would be an example of
- A.
Slump
- B.
Creep
- C.
Lahar
- D.
Rock fall
Correct Answer
A. SlumpExplanation
A slump refers to the sudden downward movement of a mass of material along a curved slope. In this scenario, large chunks of land are falling down the slope simultaneously, indicating a slump. This type of movement usually occurs in cohesive materials, such as clay or silt, and is often triggered by factors like heavy rainfall, erosion, or human activities. The abrupt and simultaneous nature of the land movement distinguishes it from other options like creep (slow continuous movement), lahar (mudflow caused by volcanic activity), or rock fall (falling of individual rocks).Rate this question:

Rocks tumbling down a steep slope would be an example of
- A.
Mudflow
- B.
Creep
- C.
Slump
- D.
Rock fall
Correct Answer
D. Rock fallExplanation
A rock fall occurs when rocks detach from a steep slope and tumble down due to the force of gravity. This can happen due to various factors such as weathering, erosion, or seismic activity. Unlike other options, such as mudflow, creep, or slump, a rock fall specifically involves the movement of rocks.Rate this question:

A fast moving mix of water, soil and rocks would be
- A.
Slump
- B.
Creep
- C.
Landslide
- D.
Mudflow
Correct Answer
D. MudflowExplanation
A fast-moving mix of water, soil, and rocks would be a mudflow. This is because mudflows are a type of mass wasting or landslide event where a mixture of water and loose sediment flows rapidly down a slope. Unlike other types of landslides, mudflows have a high water content, which makes them highly fluid and capable of traveling long distances. They often occur after heavy rainfall or in areas with saturated soil, causing the loose material to become unstable and flow downhill.Rate this question:

- 6.
Which type of mass movement moves the slowest?
- A.
Mudflow
- B.
Creep
- C.
Slump
- D.
Rock fall
Correct Answer
B. CreepExplanation
Creep is the correct answer because it is a type of mass movement that occurs very slowly over time. It involves the gradual downslope movement of soil and sediments, often due to the expansion and contraction of materials caused by freezing and thawing or wetting and drying. Unlike other types of mass movements like mudflows or rock falls, creep is characterized by its slow and continuous nature, making it the slowest type of mass movement.Rate this question:

What is deforestation?
- A.
The removal of trees
- B.
The planting of trees
- C.
The type of mass movement caused by trees
- D.
When forests are covered in mud
Correct Answer
A. The removal of treesExplanation
Deforestation refers to the removal of trees. This process involves the clearing or cutting down of forests, either for commercial purposes like logging or for creating space for agriculture, urbanization, or infrastructure development. Deforestation has significant environmental impacts, including habitat destruction, loss of biodiversity, soil erosion, and contribution to climate change through the release of carbon dioxide.Rate this question:
-
- 8.
What causes all mass movement
- A.
Rain
- B.
Snow
- C.
Gravity
- D.
Deforestation
Correct Answer
C. GravityExplanation
Gravity is the force that causes all mass movement. It is the force that pulls objects towards each other. In the context of mass movement, gravity plays a crucial role in pulling loose materials, such as rocks, soil, or debris, downslope. This can result in various types of mass movement, including landslides, rockfalls, or mudflows. While factors like rain, snow, and deforestation can contribute to the instability of slopes and increase the likelihood of mass movement, gravity is the underlying force that ultimately causes the movement to occur.Rate this question:

What is the angle of repose?
- A.
The angle at which material flows up hill
- B.
The angle at which material falls down
- C.
The steepest slope at which material no longer moves downhill
- D.
The angle of a volcano's slope that can help trigger an eruption
Correct Answer
C. The steepest slope at which material no longer moves downhillExplanation
The angle of repose refers to the steepest slope at which material no longer moves downhill. It is the point at which the force of gravity pulling the material downhill is equal to the frictional force resisting its movement. Once the material reaches this angle, it will remain in place rather than continuing to slide or flow downhill.Rate this question:

What is mass movement?
- A.
When rain causes the land to become very muddy and flow across the land
- B.
When rivers carry pieces of dirt and sediment
- C.
When gravity causes material to move uphill
- D.
When gravity causes material to move downhill
Correct Answer
D. When gravity causes material to move downhillExplanation
Mass movement refers to the process where gravity causes the movement of material downhill. This can occur due to various factors such as the saturation of the soil with water, earthquakes, or human activities like construction. When the force of gravity exceeds the strength of the material or the friction holding it in place, the material starts to move downhill. This can result in different types of mass movements like landslides, rockfalls, or mudflows, depending on the characteristics of the material and the slope.Rate this question:

Why do heavy rains help cause mass movement?
- A.
They cause the plants to grow
- B.
They cause the soil to be wet and heavy
- C.
They cause the animals to come out of their homes
- D.
They cause strong winds
Correct Answer
B. They cause the soil to be wet and heavyExplanation
Heavy rains help cause mass movement because they cause the soil to become wet and heavy. When the soil becomes saturated with water, it loses its stability and cohesion, making it more prone to erosion and movement. The added weight of the water increases the gravitational pull on the soil, making it easier for it to slide or flow downhill. This can lead to landslides, mudslides, and other types of mass movement.Rate this question:

___________________ like those in California can cause mass movement
- A.
Loud noises
- B.
Sand dunes
- C.
Heavy traffic jams
- D.
Earthquakes
Correct Answer
D. EarthquakesExplanation
Earthquakes can cause mass movement because they generate strong vibrations and shaking of the ground, which can dislodge and destabilize rocks, soil, and other materials. This can lead to landslides, rockfalls, and avalanches, causing large-scale movement of debris and mass wasting. The intense shaking during an earthquake can also liquefy loose or saturated soil, further contributing to mass movement. Therefore, earthquakes have the potential to trigger significant changes in the landscape and pose a threat to human lives and infrastructure.Rate this question:

Why is building houses on hills in landslide danger zones not a good idea?
- A.
The houses' added weight can cause landslides
- B.
The houses' noise can cause landslides
- C.
The animals like dog's can dig holes in the ground that can cause landslides
- D.
All of the above
Correct Answer
A. The houses' added weight can cause landslidesExplanation
Building houses on hills in landslide danger zones is not a good idea because the added weight of the houses can cause landslides. The weight of the structures puts additional pressure on the already unstable ground, increasing the risk of a landslide occurring. This can be particularly dangerous in areas prone to landslides, as it can lead to property damage, loss of life, and displacement of residents. Therefore, it is important to avoid constructing houses in such areas to minimize the risk of landslides.Rate this question:

Why is planting trees on a muddy slope a good idea to prevent mudflows and landslides?
- A.
The tree roots soak up water
- B.
The trees keep the soil in place
- C.
Trees add homes for wildlife
- D.
Just a and b
- E.
A, b, and c
Correct Answer
D. Just a and bExplanation
Planting trees on a muddy slope is a good idea to prevent mudflows and landslides because the tree roots soak up water, reducing the amount of water in the soil. This helps to stabilize the soil and prevent it from becoming too saturated and prone to sliding. Additionally, the trees act as anchors, keeping the soil in place with their roots and preventing erosion. This combination of reducing water content and stabilizing the soil makes planting trees on a muddy slope an effective way to prevent mudflows and landslides.Rate this question:
