Answer:

1. The lack of precipitation as well as heavy downpours cause disasters of different types, ranging from extreme drought to unprecedented flood. Climate changes, environmental degradation, population growth, urbanization and augmenting poverty cause human society to be more vulnerable to flood and drought disasters.

2. When the person at once gets out of the car. the water vapour in the atmospheric air comes in contact with the spectacles: it cools down and condenses forming very small tiny water droplets. this results in foggy appearance on the spectacles.

3. Prices of foodgrains, fruits and vegetables rise during floods or droughts because during these calamities there is a scarcity of food as heavy rainfall (which causes floods) destroy the crops and due to droughts (when there is no rainfall from many days) the crops can't be grown.
