“Weathering refers to processes that break the rocks into smaller and smaller pieces”.
Does weathering provide some benefits also ? Explain.
Answers
Answer:
yes
Explanation:
only weathering process is taken we can get soil without soil no plants will grow
Answer:
Weathering attacks the crystal boundaries of a rock.
Granite for instance, will disaggregate into individual crystals as the covalent bonds along the crystal boundary are stripped of electrons. Whether the feldspar is converted to clay or the crystal to crystal bonds break you end up with a pile of crystals. Over time the feldspars convert to clay and are the first to winnow away either by wind or water. The quartz is left behind and makes the first steps on its long journey to the beach were it will stick to some babes bikini clad bottom.
The above case would be chemical weathering and if the rock was buried, the process would be sped up by the higher moisture and the presence of humic acids in the soil. If you have been to a granite batholith, small depressions in the surface of the granite will eventually weather down to form large and small bathtub looking depressions called hexen kessels, or witch's cauldrons.
Below are Hexen Kessels on Old Rag Mountain in the Virginia Blue Ridge. When I visited them in the 70’s they were dry. You can see the granite “sand” in the bottom.
The moisture in the kettles does the weathering.
In areas were ice forms, mechanical weathering or frost and ice wedging act on the rock itself on on the crystals through differential expansion.
Below is granite sapprolite, or rotten granite weathered into dissaggregated pebbles and crystals in the soil.
