What is the process called when water soaks down through soil?

• A. Infiltration
• B. Perculation
• C. Evaporation
• D. Transpiration

Answer: (A)

The process through which water moves downward through soil is called infiltration. Infiltration occurs when precipitation or surface water seeps into the ground, allowing it to move through the soil layers and recharge groundwater aquifers. This process is crucial for maintaining the natural water cycle, as it helps to filter and purify the water while also replenishing groundwater supplies. Infiltration is influenced by various factors, including soil type, vegetation cover, and land use. For example, sandy soils typically allow for faster infiltration compared to clay soils, which can be denser and lead to slower water movement. Understanding infiltration is vital for water resource management and for practices such as stormwater management, agriculture, and conservation efforts. The other processes listed—percolation, evaporation, and transpiration—are related to the movement of water in different contexts and stages of the water cycle. Percolation generally refers to the movement of water through soil layers, but it specifically describes the downward flow process that follows infiltration. Evaporation is the process of water turning into vapor and leaving the surface, while transpiration refers to the release of water vapor from plants into the atmosphere. These terms represent distinct processes that differ from the initial soaking of water into the soil.
