Effects of landslides:
The areas worst hit by landslides are deep slopes, low lying areas of the rivers flowing from hill slopes and settlements on the areas from where river flows. Following are the bad effects of landslides:
Land slides destroy anything which come in their way. Landslides damage the roads, communication lines, human settlements, agricultural land, crops etc., The rails break, traffic is disrupted and development activities affected.
Loss of lives and property:
On the basis of the location of landslide human life and property is destroyed. Big landslide have sometimes taken thousands of peoples lives. (MP Board 10th Social Science Chapter 6 imp questions Solutions)
What are the causes of Tsunami? (MP Board 2009)
Explain the causes of Tsunami?
The sea water is never calm. Movements in the sea water is a common phenomenon. Earthquake and volcano when appear near the sea area then occurs Tsunami disaster. When the process of volcanic eruption and earthquake takes place in the base of the sea then the movements in the sea waters increase, as a result of this high waves are produced in the sea water which are in turn responsible for loss of lives and property.
What do you mean by the prevention of effect of disaster?
The prevention and reduction of their effects of the disaster are discussed under the following heads:
- Prepare plan for land use.
- To prevent people from settling in risky areas.
- To construct buildings which can resist the risks involved in the disaster (e.g. earthquake proof building etc.)
- To find out ways and means to minimise the ill effects of the disaster before their occurrence.
- Community awareness and education.
How are landslides among the major natural disasters in the world?
- Landslides are among the major natural disasters in the world.
- In hilly terrains of India, including Himalayan mountains landslides are major and widely spread natural disasters.
- They strikes life and property almost perennially and occupy a position of major concern.
- These landslides, year after year, bring about untold misery to human settlements and cause devastating damages to transportation and communication network.
How are disasters classified in India? (2010)
In India disasters may be classified as under:

Enumerate the factor that cause landslides?
Factors causing Landslides:
Landslides occur due to the interplay of several factors. They are classed as under:
- Intensity of rainfall
- Steep slopes
- Stiffness of, slopes
- Highly weathered rock layers
- Soil layers formed under gravity
- Seismic activity
- Poor drainage.
Man – made Factors:
- Deforestation leading to soil erosion
- Non – engineered excavation
- Mining and quarrying
- Non – engineered construction
- Land use pattern (faulty).
How can the risk of landslides be reduced?
The potential for landslides and destructive erosion can be greatly reduced by adopting the following measures:
- Proper development.
- Adoption of sound construction techniques.
- Erection of retaining walls.
- Avoiding steep slopes for construction of buildings.

Describe the human factors for drought disaster?
Human factors responsible for drought: The drought comes gradually and it is difficult to decide the duration of its beginning and end. The dividing level of rains, diminishing ground water level, dry well, rivers and reservoirs and weak crop give a warning of the imminent danger of drought. Although drought is a natural calamity but the main factor responsible for it are as follows:
- Ignore land management.
- Ignoring traditional sources of irrigation viz tanks, wells, reservoirs, etc.
- Destruction of community forests.
- Natural water resources get dried due to destruction of forest, due to insufficient rains the ground water level goes down; water level in the ground water level goes down; water level in rivers also goes down.
- Fodder shortage for cattle.
- Drastic changes in rotation of crops.
- Imbalanced relationship with atmosphere (ecology) results in excessive demand for water in the agriculture, industry and cottage industry.
- Faulty management of water resource.
How do floods in Bangladesh become disasters? Give an example of such disasters?
Bangladesh is a riverine country where recurrent flooding is both common and necessary. Every year large areas are submerged during the monsoon season and fertilized by deposits of fresh alluvium. If the waters remain stagnant for too long, these beneficial floods become major disasters.
- In the summer and fall of 1974 when flooding extended over nearly 50% of the country and stagnated for more than a month.
- At least 1,200 people died in the floods and another 27,500 died from subsequent disease and starvation.
- Approximately 425,000 houses were destroyed or severely damaged.
- A total of 36 million people suffered severe hardship and losses due to the disaster.
What are the main reasons of floods? Discuss the effects and effected region in India?
Main reasons of floods in India are leakage or cracking of bunds, dams etc. and releasing excess water from barrages. The danger of floods is also increasing because of defective construction of bunds, old dams etc. The water that are flowing from Himalayan rivers bring with them large quantities of soil and this is deposited on the land and areas near the sea coast.
According to an estimate, every year 10 lakh cubic feet of soil gets mixed up with the waters of rivers Gandak and Sarayu flowing from the Himalayas. This soil is deposited on the plains of Uttar Pradesh. Consequently the bottom of the rivers and their water surface is coming up. Thus every year the flow of these river is taking the form of floods.
In the mountainous regions, the river flow gets blocked due to landslides and water reservoirs are formed; then suddenly they crack and floods occur. In the Himalayan region landslides are common. In the mountainous regions the land has become unstable due to construction of roads, deforestation, uncontrolled cutting of roads, deforestation, uncontrolled cutting of hills etc. In the Himalayan area on an average 60,000 cubic meter soil is removed in construction 1 km long road. So far 50,000 kilometers of road has so far been constructed in the Himalayan region. This soil accumulation is also a cause of floods.
Flood regions in India: (10th Social Science Chapter 6 Solutions pdf)
Floods are a regular featured in India. The vast plains and coastal areas suffer from the devastation of floods. Floods are a regular annual feature in the states of Assam, Meghalaya, Arunachal Pradesh, Tripura, West Bengal, Bihar and Orissa in the North-east India. The consequences of this are suffered by both, the human and cattle population.
Effects of floods:
Floods affect the life of human beings in the following manner:
1. Physical harm:
The flood waters harm the buildings, some buildings are razed to the ground. There is danger to the lives and property-. Landslides also occur due to heavy down pour of rains and flowing water.
2. Deaths and public health:
People and cattle drown/die in the flood waters. Epidemic, diarrhoea, bacterial, infections, malaria, etc. spread.
3. Hindrance in water supply:
The water sources get contaminated and there is problem in supply of potable water.
4. Crops and food supply:
The fields (crops) are inundated and the grain godowns are also harmed and damage is caused to food grains.
5. Change in the soil structure:
The soil is also affected and due to sea water there is a danger of soil becoming salty.
