Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What effects does global warming have on the hydrologic (water) cycle?
A
Increases the rate of evaporation from land
B
Increases the rate of evaporation from the sea
C
Increases the amount of water vapor the atmosphere can hold
D
All of the above
Explanation: 

Detailed explanation-1: -Rising global temperatures as a result of climate change are causing water to evaporate faster. This is accelerating the water cycle, which could have a significant impact on our seas and on the continent, according to new research.

Detailed explanation-2: -In general, warming is expected to accelerate the hydrological cycle, speeding hydrological processes up. Temperature rise enhances evapotranspiration, precipitation, and intense precipitation. Evaporation is a complex process, dependent on several factors.

Detailed explanation-3: -Increased global temperatures lead to increased evaporation, thus increasing the rate of the hydrologic cycle. Increased evaporation creates more clouds and more precipitation forming as rain rather than snow due to the increased temperature.

Detailed explanation-4: -Global warming causes the hydrologic cycle to accelerate. Where is most of the Earth’s fresh water stored today? Most of the Earth’s fresh water is stored in Polar Ice Sheets.

Detailed explanation-5: -A significant amount of the energy the Earth receives from the Sun is redistributed around the world by the hydrological cycle in the form of latent heat flux1. Changes in the hydrological cycle have a direct impact on droughts, floods, water resources and ecosystem services.
