The plates can be separated with a little effort by prying the horizontal layers with a pen knife. This structure is commonly found in compacted soil. It is commonly found in forest soils, in part of the A- horizon, and in claypan* soils. Clay's soil particle shape is flat, or plate-like; meaning it's good at stacking on top of each other and creating a very "tight" soil. No public clipboards found for this slide, Student at Stamford University Bangladesh. They are named after the major continents and ocean floors that they encompass. Plate-Like Plate-like soil structure is usually found in compacted soil and the cracks are stretched more horizontally than they are vertically. They are generally oriented horizontally.
