How does human activities cause drought and flood ?
Answers
Answer:
Removing trees and vegetation reduces the amount of moisture in the atmosphere making the area drier. Constructing dams and reservoirs reduces the flow of water downstream. This can lead to drought in other areas.
Constructing buildings and surrounding roads and paths creates impermeable surfaces which increase surface run-off. Drains also increase the flow of water into surrounding rivers, increasing the flood risk.
Answer:
Droughts and floods are the most common natural disasters in coastal or riverine land areas.
Human works are also responsible for these hazards. Because
1) Human works are degrading the soil of the river banks which increases the chances of flood.
2) Air pollutants which are created by the industrial sectors, are decreasing the rainfall amount which is a major reason behind the droughts.
Explanation:
Human activities are generally responsible for causing many hybrid disasters. Human activities such as overconsumption, wastage and pollution of water are all responsible for causing droughts.
