Okra Mucilage on Handmade Recycled Paper

   Simple properties of rocks for field-testing.
   Classification
  * Common rock minerals. These are the building blocks of rocks and precious stones.
  * Clay layer structures. Clay is one of the most important minerals for mankind.
  * Igneous rocks. Molten rock comes from deep in the earth and transforms into various rock types.
      * Classification of igneous rocks. One type smoothly grades into the next; intrusive and extrusive rock.
      * The processes inside a magma chamber. Inside gigantic cauldrons, many kinds of rock are formed.
      * Mineral formation from solid solution, describes part of the process in a magma chamber.
  * Sedimentary rocks. Erosion by water and wind, transport and sort soil components.
      * Particle sizes: definitions for names of particles from boulder to silt.
      * Sediment composition triangle: defining sedimental rock type from sand, clay and carbonate content.
  * Metamorphic rocks. Under pressure and heat, sedimentary rock transforms into new forms.
   Soils of the world. Soils are the most variable of minerals, but there are some general classes.
  * Classification of soils: their names, structures and properties
  * Carbon fluxes and pools in terrestrial ecosystems, compares productivity and carbon pools.
  * Properties of soil: texture, structure, moisture, etc.
  * Soil degradation: a systematic classification of the many ways soil is lost.
  * Soil timescales: time scales in the history of soils
   Rock and soil chemistry.
  * Properties of soil: soil components, texture, structure, pore space, moisture, pH, CEC and more.
  * Soil degradation: a comprehensive summary of the many ways soil degrades and is lost in both quantity and quality
  * Soil time scales: tectonic movement, profile formation, soil formation, and more.
  * Rock and soil chemistry: Bowen series, solid solution, cation exchange capacity and more.
