Interdependence with physical & chemical weathering
1Physical weathering involves action of heat and rain which breaks stress and leads to cracks.
2Acids from rain like carbonic acid, sulphuric and nitric acid enter the cracks in rock to cause chemical weathering.
3These cause corrosion for rocks and convert these into fragments & sediments.
4Physical weathering also leads to conglomeration through pressure.
5Chemical weathering leads away certain elements and cause enrichment.
6Both together aid mass wasting & erosion.
Weathering is a process that measurably distorts and/or degrades [materials/substances] of [significance to society].
