Which of the following pairs is correctly matched regarding water movement? 1. Infiltration : Seepage of rainwater into the ground 2. Runoff : Water flowing into drains from concrete roads 3. Precipitation : Water falling as rain or snow Select the correct answer using the code given below:

The correct option is 1, 2 and 3 . Explanation The fundamental processes within the hydrological cycle (water cycle), which describes the continuous movement of water on, above, and below the surface of the Earth. Statement-wise Analysis: - Statement 1 is Correct: Infiltration is defined as the process by which water on the ground surface enters the soil. It is the primary mechanism through which groundwater is recharged and soil moisture is replenished. - Statement 2 is Correct: Runoff (or surface runoff) is the flow of water that occurs when excess stormwater, meltwater, or other sources flow over the Earth's surface. This typically happens when the soil is saturated to full capacity or when the surface is impermeable, such as concrete roads, causing water to flow into drains rather than seeping into the ground. - Statement 3 is Correct: Precipitation refers to any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include rain, snow, sleet, and hail. Key Takeaway: The hydrological cycle relies on distinct physical processes: Precipitation delivers water to the surface, Infiltration moves water into the soil profile, and Runoff transports excess water across the surface to water bodies.

Solution

The correct option is

1, 2 and 3

Explanation

The fundamental processes within the hydrological cycle (water cycle), which describes the continuous movement of water on, above, and below the surface of the Earth.

Statement-wise Analysis:

Statement 1 is Correct: Infiltration is defined as the process by which water on the ground surface enters the soil. It is the primary mechanism through which groundwater is recharged and soil moisture is replenished.
Statement 2 is Correct: Runoff (or surface runoff) is the flow of water that occurs when excess stormwater, meltwater, or other sources flow over the Earth's surface. This typically happens when the soil is saturated to full capacity or when the surface is impermeable, such as concrete roads, causing water to flow into drains rather than seeping into the ground.
Statement 3 is Correct: Precipitation refers to any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include rain, snow, sleet, and hail.

Key Takeaway:

The hydrological cycle relies on distinct physical processes: Precipitation delivers water to the surface, Infiltration moves water into the soil profile, and Runoff transports excess water across the surface to water bodies.
