Detailed explanation-1: -The hydrologic cycle largely depends on the solar energy to the Earth, because hotter temperatures result in more evaporation, precipitation and higher humidity. With the concerning emissions of greenhouse gases, global warming will likely play a large effect on this important cycle.

Detailed explanation-2: -The Availability of Water Forests can also help reduce the impacts of flood from storms by blocking and slowing down the flow of runoff. Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding. While deforestation may occur locally, its effect is global.

Detailed explanation-3: -Changes in the shape and size of urban streams, followed by decreased water quality, are the most visible effects of increased imperviousness. Greater frequency and severity of flooding, channel erosion, and destruction of aquatic habitat commonly follow watershed urbanization.

Detailed explanation-4: -Burning fossil fuels and the hydrological cycle Glacial melt and precipitation rates are affected, which changes river discharge, leading to an increased risk of flooding in the winter and drought in the summer.
