Final answer:
Evaporation and transpiration are the two water cycle processes that defy gravity, with both involving water moving upwards against gravity due to the heat of the sun and plant physiology.
Step-by-step explanation:
The two processes in the water cycle that defy gravity are evaporation and transpiration. Evaporation occurs when the sun's energy heats surface water, causing it to turn into water vapor and rise into the atmosphere. Transpiration takes place when water is absorbed by plant roots, moves up through the plants, and then is released as water vapor from the leaves into the air. Both processes involve water moving upwards against gravity.
