In the described science activity, what natural process do the students best understand by watering their mounds of sand and dirt?

Abrasion
Deformation
Erosion
Subduction

The correct answer is: Erosion

Watering mounds of sand and dirt allows students to observe erosion in a concrete way. When water is applied to these structures, it demonstrates how water can transport and remove soil and sand particles, reshaping the landscape over time. This hands-on experience helps children visualize the effects of moving water on landforms, showing them how the surface materials can be worn away or carried to different locations by flowing water. Erosion is a fundamental geological process that explains how weathering and movement of soil and rock happen when water interacts with the ground. By engaging in this activity, students can directly see the results of this natural process, including potential changes in the shape and structure of their mounds. Thus, the activity embodies the concept of erosion effectively, as it involves transferring materials from one place to another, illustrating the impact of natural forces in a simple and engaging manner.
