3. Formation of oxides takes place, except the noble gases Oxygen form oxides with all other elements. For example, oxide of hydrogen, silicon dioxide,etc.
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.
14. These broken pieces of rocks are called sediments and word sedimentary is derived from sediments.
16. Soil is defined as the mixture of weathered rocks and organic material. Soil is produced from process of weathering and and natural erosion.
17. Rock forming minerals include fled-spars, calcite, quartz, mica, dolomite, etc.
Answer16: False
Comments: The organic amendments (manure, bio-solid, wood ash, compost grass clipping etc.) improve the physical, chemical and biological properties of the soil. It also supplies the essential nutrients needed for plant growth. It can also support the beneficial bacterial growth in the soil but not enhance the growth of harmful microorganisms (bacteria and fungi) in the soil.
