    The shape of a rock particle can be expressed in terms of 3 independent properties: form, roundness and surface texture These form a 3tiered hierarchy of observational scale, and of response toWhy is the size of rock particles important in soil structure? T he size of rock particles are important to soil structure because the larger particles of sand allow rainwater to drain quickly through the soil, while the smaller particles of clay prevent rapid drainage What kind of soil does Canada have? Four main soil orders are associated with forested landscapes throughout Canada: OrganicWhy is the size of rock particles important in soilThe size, shape, density and spatial arrangement of those particles, alongside with natural fractures and cracks (although those are certainly not exclusive to carbonate rocks), define a microstructural pattern that is known to have a great influence on rock physical properties Thus, to understand carbonate rock systems at large scalesMicrostructures and physical properties in carbonate rocks
