Soil Science Concepts and Processes

In this SciShow Kids episode, Squeaks and the host discuss their nature walk observations, focusing on soil formation. They explain how soil is created from rocks through weathering by natural forces like wind and water, and how organic matter contributes to soil quality. Different types of rocks produce various soil types, such as sand and clay. The episode encourages viewers to observe and record soil changes in their environment, promoting hands-on learning. The video concludes with a mention of their partnership with Soil Cycle, a composting initiative in Missoula, Montana.
