| 1. | It is considered unfeasible to determine the geotechnical characteristics of this soil layer.
|
| 2. | Surface detritus facilitates the capture and infiltration of rainwater into lower soil layers.
|
| 3. | But as the soil layer thickens, this process is slowed down.
|
| 4. | My textbook say at summer arctic tundra only upper soil layer melts permafrost.
|
| 5. | The soil layer contains an amended soil mix that can support vegetative growth.
|
| 6. | Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud.
|
| 7. | Above the normal soil layer was a very stony layer.
|
| 8. | Therefore, soil layers, and in turn soil biota, are conserved in their natural state.
|
| 9. | They may also be used to transfer building loads past weak or compressible soil layers.
|
| 10. | Interface between these two soil layers is very clear.
