Soil Porosity: Sand, Silt, and Clay | Science project

Soil Porosity: Sand, Silt, and Clay. Soil texture is determined by the relative proportion of sand, silt, clay and small rocks (pebbles) found in a given sample. Sand is gritty to the touch and the individual grains or particles can be seen with the naked eye. It is the largest of the three size classes of soil particles.

Glauconite

Glauconite is an iron potassium phyllosilie (mica group) mineral of characteristic green color which is very friable and has very low weathering resistance.. It crystallizes with a monoclinic geometry.
