In this episode of SciShow Kids, Squeaks and the host explore the origins and formation of soil. They discuss how soil is created from rocks through weathering by natural forces like wind and water. The episode also covers different types of soil, such as sand and clay, and the role of organic matter in soil fertility. Viewers are encouraged to observe soil in their environment and become 'neighborhood soil scientists.' The episode concludes with a mention of the partnership with Soil Cycle, a composting initiative in Missoula, Montana.
