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

Step 1: Recall the sequence of steps in the hydrological (water) cycle.
The water cycle describes how water moves between the atmosphere, land, and water bodies. The commonly taught above-ground sequence is: water evaporates from oceans, rivers, and lakes (evaporation), rises and cools to form clouds (condensation), and then falls back to the ground as rain, snow, or hail (precipitation).
Once precipitation reaches the ground, a separate below-ground sequence takes over: some rain is first caught by tree canopies and vegetation before it reaches the soil (interception), the rest that reaches bare or vegetated ground soaks into the topsoil (infiltration), and water that keeps moving downward through soil layers reaches deeper groundwater storage (percolation), eventually adding to the aquifer (aquifer recharge).

Step 2: Check option (A), Evaporation to Condensation to Precipitation.
This is exactly the standard above-ground cycle: water vapour rises (evaporation), forms clouds (condensation), and falls back as rain (precipitation). The order is correct, so option (A) is a valid sequence.

Step 3: Check option (B), Precipitation to Infiltration to Interception.
When rain falls on a vegetated area, it is caught by leaves and branches (interception) before whatever passes through reaches the soil and soaks in (infiltration). Interception happens before infiltration, not after. Option (B) places infiltration before interception, reversing the actual order, so this option is wrong.

Step 4: Check option (C), Condensation to Percolation to Infiltration.
Percolation, the deep downward movement of water already in the soil, can only happen after water has entered the soil, which is what infiltration means. Infiltration must come before percolation, not after, so this order is wrong. Condensation, cloud formation, also has no direct sequence link straight to underground percolation, since precipitation and infiltration happen in between.

Step 5: Check option (D), Infiltration to Percolation to Aquifer Recharge.
Water first enters the soil surface (infiltration), then moves further down through the soil profile (percolation), and finally reaches and adds to the saturated groundwater zone (aquifer recharge). This is the correct order for the underground part of the water cycle, so option (D) is valid.

Final Answer:
Options (A) and (D) both describe a correct order of water cycle processes; (B) and (C) reverse the true sequence.
\[ \boxed{\text{(A) and (D), i.e. options 1 and 4}} \]
