Which of the following is not part of the water cycle?
a. water infiltrating into the soil and bedrock
b. water evaporating from a lake
c. water moving into creeks and streams following a rainstorm
d. calcium carbonate dissolving in soil water and groundwater

Option (D)

Explanation: In the water cycle, water is transported from the oceans, seas and lakes to the atmosphere, which then again falls back due to precipitation.

       Plants also absorbs water by their roots and releases back into the atmosphere by evapo-transpiration process. Some of the water gets percolated into the ground and gets mixes up with the groundwater.

     Thus all the provided options fulfills the condition for water cycle except the last one, i.e dissolution of CO₂ in the ground water or the land surface is not considered to be a part of water cycle.

Hence the correct answer is option (D).
