As you all know, nature can be fascinating, more specific, biology. Soil for me was the most fascinating and I was curious, what does soil look like up close?

The soil is my first sample during a vacation. For some reason, it looked like soil was nothing on a Foldscope, although it looked like it was something. This fascinated me, so I took a closer look. Microscopic dirt is there. Once I found out, I became more curious about the soil. What is in there? Is there more types of soil in this world?
