clay
Clay particles have the smallest pore spaces compared to sand and silt particles, thereby allowing for the least porosity in soil.
The percentage of air in soil varies depending on factors like soil type, compaction, and moisture content. In general, soil samples typically contain around 25-50% of pore space, which includes both air and water.
Soil pores contain mineral matter along with organic matter, air, and water. The percentage of mineral matter in soil pores varies depending on the soil type and composition, but typically ranges from 40-60%. This mineral matter contributes to the physical structure and nutrient content of the soil.
No, type C soil is not the least stable soil. Type C soil is moderately cohesive and may require some engineering considerations for excavation. Type D soil is considered the least stable soil due to its lack of cohesion and tendency to flow when excavated.
Soil porosity refers to the amount of space between soil particles where air and water can flow. It is important for root growth, air circulation, and water infiltration in the soil. Soil porosity is influenced by factors such as soil texture, structure, and compaction.

Sandy soil has larger particles with more air space, allowing water to drain quickly and not be held as well compared to other soil types. This makes sandy soil have a low water-holding capacity.
Sandy soil holds the least amount of water because it has larger particles which allow water to drain quickly, leading to low water retention.
Clay is considered the least permeable type of soil, meaning water drains slowly through it due to its small particle size and high compaction. This can lead to waterlogging and poor drainage in clay soils.
Gravity pulls water downward through the spaces between soil particles due to the force of gravity. This process is known as infiltration, where water seeps into the ground and fills in the gaps between soil particles. The movement of water through soil is influenced by factors such as pore size, soil type, and the slope of the land.
