Interpretation is the biggest form of challenge that the reader faces
Explanation:
There are few challenges that the reader face while reading the conclusion of the text . They are :-
1. Interpretation- The reader needs the understand the Meaning of the whole writing. Otherwise the purpose of the reader of the script goes in vein. Some reader face this challenge as the conclusion is not properly formed n left fot the readers to "Connect The Dots".
2. Crux- For the detailed explanation, a conclusion is given which summarizes the whole text. Therefore if the conclusion is not clear, the reader might face the difficulty in understanding the crux of writing.
 
        
             
        
        
        
1. Evaporation happens first... that's when the warmth from the sun causes water from oceans, lakes, etc to rise into the air turning into water vapor... then the water vapor collects together to form clouds
2. Condensation: When water vapor in clouds cool down and turn back into liquid water
3. Precipitation: When the water falls from the sky, in the form of rain, snow, hail, etc.
4. Runoff: when the water goes back onto the land and back into the ground, streams, etc.
***Transpiration is when moisture is carried through plants from the roots then changes into vapor and is released into the atmosphere (im not really sure where this goes) 
Hope this helped!!!
