1.Frost Wedging (Freeze-Thaw)
Water expands by 9 percent when it freezes. As it expands, it exerts up to 4.3 million pounds per square foot of pressure. Since water seeks low points, repeated freezing and thawing can lead to deep vertical fissures as cracks are extended downward. Cracks that allow entry of roots lead to similar wedging.
2.Crystal Formation
Crystal formation cracks rock in a similar way. Most water contains dissolved salts. When water in rock fissures evaporate, the salt concentration increases, which leads to crystallization. This occurs in arid regions where the humidity fluctuates widely, so that the salt can be redissolved and carried into new fissures.

Hi
I am going to tell you a story about the water cycle.
Evaporation is what happens first. This is wear the water goes into the air. Next Condensation this were it rises into the the atmosphere. Now we go onto the sublimation this is what happens when the water contributes to the vapor in the air. We all know what comes next precipitation this is were all of the clouds accumulation and it snows or rains. Transportation well this is what it is it is absorbed by the soil. Runoff this is where something weird happens it pours down in what ever form. And finally infiltration this is were <span>Some of the water that precipitates does not runoff into the rivers and is absorbed by the plants or gets evaporated. It moves deep into the soil. This is called infiltration. The water seeps down and increases the level of ground water table. It is called pure water and is drinkable. The infiltration is measured as inches of water-soaked by the soil per hour.
Hope this helps.</span>
