A more thorough explanation:

ELUVIATION

Eluviation is the movement of soil caused by excessive water in the soil.

1. After heavy rainfall, the top layer of soil on the hillside was washed away due to eluviation.

2. The eluviation of the soil in the flood-prone area caused the crops to fail.

Eluviation occurs when water moves through the soil and carries away the top layer of soil particles. This can happen during heavy rainfall or when the soil is saturated with water. The examples illustrate how eluviation can cause soil erosion and affect crop growth.
