Answer 2

Answers:

1. rescue of the trapped (option d)
2. landslides (option b)
3. flood (option b)
4. drought (option b)
5. earthquake (option a)
6. epidemic (option c)
7. Odisha (option c)

Explanation:

• A landslide can be defined as the movement of a mass of rocks, debris, or soil down a slope. Landslide mitigation measures refer to the human activities on a slope to reduce the effect of a landslide and prevent further danger. These include modification of slope geometry, developing structures like piles and retaining walls, rerouting the way of drainage etc. Thus, rescue of the trapped (option d) is not a mitigation method.

• Landslides occur when huge masses of soil or rocks move down the slope. Therefore, when the vegetation cover is increased, the soil becomes firmer as the roots of the tree are bound to the soil. As a result, it reduces the effect of landslides. Therefore, option b is right.

• Floodwater transports sewage and septic waste, as well as agricultural waste and chemicals. As a result, the water gets contaminated and causes various diseases. Thus, option b is the right answer.

• Drought is caused by a prolonged absence of rain. As a result, the land turns dry. Plants and animals die of lack of water. Thus, option b is the right answer.

• The impact of earthquakes cannot be reduced by a warning system as they affect a particular region as a whole. Therefore, they cannot be displaced within a short period of time. Whereas, in the case of other natural disasters like volcanoes, storms, or droughts, people can be shifted to another place to prevent the harmful effects inflicted by the disasters. Thus, option a is the right answer.

• An epidemic cannot be prevented by disaster-resistant buildings as it directly affects human beings. The buildings have no role in the spread of an epidemic. Hence, option c is the right answer.

• Fani was the super cyclone that hit Orissa in 2019. It took the lives of over 40 people. Thus, option c is the right answer.
