Question

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

Answer 1

Answer:

${\small{\boxed{\red{percolation:}}}}$

Percolation refers to the movement and filtering of fluids through porous materials.

${\small{\boxed{\red{Leaching:}}}}$

(with reference to a soluble chemical or mineral) drain away from soil, ash, or similar material by the action of percolating liquid, especially rainwater.

${\small{\boxed{\red{Weathering:}}}}$

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

${\small{\boxed{\red{Runaway:}}}}$

a strip of hard ground along which aircraft take off and land.

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

$\star\pink{Leaching}\star$

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

$\star\pink{Weathering}\star$

• 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.

$\star\pink{Runaway}\star$

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