Mass Movements

Q. What is the impact of mass movements?

1. It leads to the destruction of property.
2. It leads to oxidation and rusting of rocks.
3. It leads to the peeling away of external rock surface due to pressure and temperature changes.
4. It is dangerous for human lives.

Q. Identify whether the following statements are True or False and select the appropriate option given below.

i. In solifluction, the soil is oversaturated with water and the soil particles get extremely wet.
ii. Solifluction prominently happens in tropical regions with heavy rainfall.

1. i. False
   ii. True
2. i. False
   ii. False
3. i. True
   ii. True
4. i. True
   ii. False

Q. Consider the following statements.

A - Solifluction is a rapid mass movement.

B - Solifluction prominently happens in cold and high altitude regions, particularly where the surfaces are completely frozen.

Identify the incorrect statement(s).

1. B only
2. Both A & B
3. Neither A nor B
4. A only

Q. Slow movement of soil down a slope is known as _______.

1. Soil crawl
2. Soil cast
3. Soil creep
4. Soil flow

Q. Which of the following is an example of slow mass movement?

1. Rockslides
2. Slumping
3. Landslides
4. Soil creep

Q. I could be described as a slow movement of soil down to a slope. So in my story the water is my friend. How? The water acts as a lubricant and causes the individual soil particles to move over one another and over the rocks easily. As this is a slow process, I am not very noticeable.

Who am I?

1. Solifluction
2. Slumping
3. Soil creep
4. Landslides

Q. To provide electricity to a remote village, the government installed electric poles along the roads near the slopes. However, some years later, it leaned to the side of the road, and some even collapsed with no rain or any other natural disaster occurring before the event. Why do you think this happened?

1. Contraction of the base of electric poles due to cold weather
2. Growth of moss, algae, and lichen on the slope
3. The effect of soil creep
4. Poor installation of electric poles

Q. Landslides and slumping are examples of slow mass movements.

1. True
2. False

Q. Which of the following refers to the process in which the weathered materials do not slide but sink inside the ground?

1. Soil creep
2. Solifluction
3. Slumping
4. Carbonation

Q. What is/are the factor(s) responsible for the downward movement of a large volume of rocks down the slopes of land?

1. Carbonation
2. Steepness of the slope
3. Weight and type of rock fragments
4. Rainfall conditions

Q. Which of the following refers to the process of slow movement of soil down a slope?

1. Solifluction
2. Soil creep
3. Exfoliation
4. Penetration

Q. Which of the following is/are the factor(s) responsible for the downward movement of huge volume of rocks on slopes of land?

1. Human activity
2. Flat surface
3. Humid region
