Question

how do activities cause droughts and floods

​

Answer 1

Answer:

Human activities that degrade the environment often increases flooding. These activities include: Deforestation. The lack of vegetation encourages water to flow over the surface rather than infiltrate into the soil thus increasing surface runoff.

Global warming, or climate change, is a major causing factor of droughts. It's unfortunate that human activities contribute to the emission of greenhouse gases, which in turn cause the abnormal elevation of global temperatures. ... This directly contributes to dry conditions, drier weather, and of course, droughts.

Answer 2

Explanation:

Surprisingly, deforestation can also lead to severe droughts. Trees are an important part of the water cycle, bringing ground water back into the atmosphere. The lack of plants, like deforestation, causes increased risk for flooding, soil erosion, and drought.
