The image shows three rectangular glass display cases filled with different types of soil. On the left side of the display case, there is a pile of dark brown soil, which appears to be a type of soil sample. Next to it, there are two smaller squares of soil, one larger and one smaller, which are stacked on top of each other. The larger square is larger than the smaller square and has a rough texture, while the smaller squares are smaller and have a more rounded shape. The display case is placed on a white surface, and there is some text at the bottom of the image that reads "Sealed soil and rammed earth".
