Worked Solution

Step 1: Plants contribute to the water cycle through transpiration. Step [2-9]: Transpiration releases water vapour into the atmosphere. Step [2-9]: Removing plants eliminates this source of water vapour, leading to an overall decrease in humidity and cloud formation.

Correct answer: There would be less water vapour in the air.
