Some precipitation that falls to Earth gets soaked up by soil. This water is referred to as:

• A. runoff
• B. condensation
• C. infiltration
• D. evaporation

Answer: (C)

Verified step by step guidance

1. Understand the concept of infiltration: Infiltration refers to the process by which water on the ground surface enters the soil. This is a key part of the water cycle and helps replenish groundwater supplies.
2. Differentiate infiltration from other terms: Runoff refers to water that flows over the surface of the land into rivers, lakes, or oceans. Condensation is the process by which water vapor turns into liquid water, forming clouds. Evaporation is the process where liquid water turns into water vapor due to heat.
3. Relate infiltration to precipitation: When precipitation falls to Earth, some of it is absorbed by the soil through infiltration. This process is influenced by factors such as soil type, vegetation, and the intensity of rainfall.
4. Consider the role of infiltration in the ecosystem: Infiltration is crucial for maintaining soil moisture, supporting plant growth, and replenishing aquifers. It also helps prevent excessive runoff, which can lead to erosion and flooding.
5. Review the water cycle: Infiltration is one of the processes in the water cycle, along with evaporation, condensation, precipitation, and runoff. Understanding how these processes interact can help clarify the role of infiltration in the environment.
