Give two effects increased global temperature would have on the water cycle.
1. increased rate of evaporation
2. increase in transpiration
3. increase in precipitation due to more water vapor in the atmosphere

Why is segment D-E longer than segment B-C?
It takes more energy to boil a substance than melt it because upon boiling ALL intermolecular bonds must be broken vs. during melting only a few have to be broken.
