Question

Which of the following is/are the correct order of processes in the water cycle?

• A. Evaporation - Condensation - Precipitation
• B. Precipitation - Infiltration - Interception
• C. Condensation - Percolation - Infiltration
• D. Infiltration - Percolation - Aquifer Recharge

Hint:

Split the water cycle into an above-ground leg (evaporation, condensation, precipitation) and a below-ground leg (infiltration, percolation, aquifer recharge), then check each option follows one of these two orders.

Answer 1

The Correct Option is A, D

The water cycle has two linked sequences: an above-ground sequence, how water gets into the sky and comes back down, and a below-ground sequence, what happens once it lands. Each option strings together three stages, and the task is to check whether that order is physically possible.

1. Evaporation - Condensation - Precipitation: Water turns to vapour and rises from oceans and rivers (evaporation), the rising vapour cools and clumps into clouds (condensation), and the cloud droplets eventually fall as rain or snow (precipitation). Each stage genuinely leads to the next, so this order is correct.
2. Precipitation - Infiltration - Interception: Rain lands first on tree canopies and plant leaves before it can even reach open soil, so interception physically happens before infiltration, not after it. This sequence has interception and infiltration flipped, so it is wrong.
3. Condensation - Percolation - Infiltration: Percolation, water working its way down through soil to the water table, can only happen to water that has already infiltrated into the ground. Listing percolation before infiltration puts the effect before its own cause, so this sequence is wrong.
4. Infiltration - Percolation - Aquifer Recharge: Water first soaks into the topsoil (infiltration), then keeps moving downward through subsurface layers (percolation), and finally reaches and tops up the saturated groundwater zone, the aquifer (aquifer recharge). Each stage is the direct continuation of the one before it, so this order is correct.

Testing cause and effect for each triplet shows that (A) and (D) both hold together as genuine step-by-step sequences, while (B) and (C) each reverse two stages that must occur in the opposite order.

Let's summarize:

• Above-ground water cycle: evaporation leads to condensation leads to precipitation.
• Below-ground water cycle: infiltration leads to percolation leads to aquifer recharge, with interception, canopy capture, occurring before infiltration wherever vegetation is present.

So the correct options are (A) and (D), that is, options 1 and 4.
