Question

what is
1. percolation.
2.Leaching
3. weathering.
4.Runaway​

Answer 1

1)In physics, chemistry and materials science, percolation (from Latin percolare, "to filter" or "trickle through") refers to the movement and filtering of fluids through porous materials. It is described by Darcy's law.

2)In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. ... Leaching may also refer to the practice of applying a small amount of excess irrigation where the water has a high salt content to avoid salts from building up in the soil (salinity control).

3)Weathering is the breaking down or dissolving of rocks and minerals on Earths surface.

4)1 : one that runs away from danger, duty, or restraint.

2 : the act of running away out of controlalso : something (such as a horse) that is running out of control.

3 : a one-sided or overwhelming victory.

Answer 2

$\star{Percolation}$

• Percolation is the process of a liquid slowly passing through a filter.

$\star{Leaching}$

• Leaching is a process in which water - soluble substances are washed out from the soil.

$\star{Weathering}$

• Weathering is the breaking down of rocks,soils and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water and biological organisms.

$\star{Runaway}$

• Runaway is the passing of soil and other substance by rain.
