Answer:
Explanation:Based on the information in slide #3, the accurate statement is:
b) Silt has lower porosity than clay and greater permeability than sand.
In the context of soil properties, porosity refers to the amount of open space or voids within the soil, while permeability refers to the ability of water or other fluids to pass through the soil.
The information on slide #3 suggests that silt has lower porosity than clay. This means that silt has fewer open spaces or voids compared to clay.
Additionally, the information indicates that silt has greater permeability than sand. This means that water or other fluids can pass through silt more easily than through sand.
It's important to note that the other options are not accurate based on the information in slide #3. Sand does not have higher permeability than silt or greater porosity than gravel. Clay does not have higher permeability than silt or lower porosity than sand. And sand does not have less porosity than clay or greater permeability than silt.
I hope this helps clarify the accurate statement based on the information in slide #3. Let me know if you have any further questions!
