Knowing About Our Soil - Physical (8) , Chemical (2) and Biological (1) Characteristics of Soil
Characteristics of Soil
Angular and Subangular
- Angular blocky: Three dimensions are about same size but edges are shape and faces appear flattened.
- Subangular blocky: Three dimensions are about same size but polythedrons are subarounded.
Munsell Color System

- 100 equally spaced hues around circle.
- Brightness: Value from 0 for black to 10 for white
Porosity vs. Permeability
These are two distinct physical properties of solids.
- Porosity:
- Measure of how much of a rock is open space.
- This space can be between grains or within cracks or cavities of the rock.
- Refers to the extent to which tiny pores or spaces exist within the solid.
- Permeability:
- Measure of the ease with which a fluid can move through a porous rock.
- Refers to the ability of a mass of solid to permit or restrain the passage of fluids.
- That is gases or liquids, through itself.
