4.Runaway​

Answer 1

Answer:

ANSWER

A liquid when slowly passes through a filter, this is called percolation.

Leaching is the natural process by which water soluble substances (such as calcium, fertilizers, pesticides) are washed out from soil or wastes in the downward passage from upper soil layer to lower soil strata.

Breakdown of rocks at the Earth's surface, by the heavy rainfall, extremes of temperature, and biological activity is called weathering.

Runaway is the passing of soil and other substances by rain.
