| 11. | In protected areas, allochtonous sandy parent materials from tsunami deposits may be found.
|
| 12. | B ) Subsoil : Subsurface layer reflecting chemical or physical alteration of parent material.
|
| 13. | They form quickly through alteration of parent material.
|
| 14. | A catena can form on various underlying or parent materials and in different climates.
|
| 15. | The texture, pH and mineral constituents of saprolite are inherited from its parent material.
|
| 16. | Parent material transported by streams is called alluvium of which there are three main types.
|
| 17. | Parent material becomes hydrolyzed by the acidic solution to produce minerals and to release cations.
|
| 18. | Phase transformations normally result in the creation of an interface between the transformed and parent material.
|
| 19. | They are : parent material, climate, topography ( relief ), organisms, and time.
|
| 20. | Soils formed from lacustrine parent material have low permeability in part because of this high clay content.
