I don't think the water cycle has a beginning or ending because all the water in the world is always in various stages of the cycle. It's kind of like asking if a circle has a beginning or ending.
At the very least, I can't think of a specific 'beginning' or 'ending', although I suppose there is an argument to be made that percipitation is the ending and evaporation is the beginning.
The blending of different disciplines like geology, biologists, hydrologists and foresters can present both challenges and opportunities to the environmental scientist. The discipline like geology can involve someone used to mining and the destruction of ecosystems like mining down through lakes in open pit mines which is detrimental to the environment, but on the other hand the geologist can choose the best soil for growing grass on to feed the wild deer and moose on the reclaimed waste dumps, for example.

To solve this question you need to know the specific heat of the object, which is water. The specific heat of water is 1 calorie/gram °C = 4.2<span>joule/gram °C. The energy needed would be:
Q= c*</span>m*ΔT
Q= 1 calorie/gram °C * 250 g * (85-25°C )
Q= 15000 calorie= 63000J
