| 1. | Rhizoliths are created through processes of chemical weathering, decomposition, reprecipitation and cementation.
|
| 2. | Once deposited, physical and chemical weathering can alter the state of preservation.
|
| 3. | Quartzite is also very resistant to chemical weathering and can form ridges.
|
| 4. | Chemical Weathering ( talk ) 13 : 44, 17 December 2008 ( UTC)
|
| 5. | On Earth, all chemical weathering reactions involve water to some degree.
|
| 6. | Water is essential for all the major chemical weathering reactions.
|
| 7. | This is because chemical weathering requires the presence of water.
|
| 8. | Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops.
|
| 9. | Basalt rock is prone to chemical weathering contributing more TDS to the river water.
|
| 10. | Deposits of detrital colluvium can reveal the soil composition and signify processes of chemical weathering.
