Which layer will become saturated first when rain falls?

clay
granite
rocks
soil

Answer 1

The layer that will become saturated first when rain falls is the **soil**. Soil is made up of particles that can absorb water, allowing it to become saturated more quickly than the underlying layers of clay, rocks, or granite. Once the soil reaches saturation, additional water may then move downward into the clay layer.
