Concept:Soil texture is the physical property that remains stable over long periods.
Explanation:Soil texture describes the proportions of sand, silt, and clay particles in the soil.
Farming practices and natural processes can change soil colour, depth, and organic matter content fairly quickly.
However, the mineral particle size distribution that defines texture changes only through very slow processes like weathering.
Hence, among the given options, texture is the most permanent physical property of soil.
