6. Weathering is defined as the chemical and physical breakdown of rocks.
8. Acetic and citric acid dissolves calcite. However, it can also be dissolved by groundwater depending upon the factors such as temperature of water, pH value of water and concentration of ions dissolved.
10. Grinding away of rock with other rocks is called Abrasion. It is mainly caused by movement of wind and on surface stone or rocks against the surface of rock.
13. It is Chemical weathering which breaks down the rocks and also changes mineral composition of newly formed rock from it's parent rock.
