Understanding Rocks and Soil

The video introduces Bill and Sandy, discussing the transformation of rocks into soil through erosion and weathering. It explains how soil is formed from broken-down rocks and microscopic organisms. The video also covers the process of erosion, which reduces rocks to sand over thousands of years. Finally, it explores metamorphic rocks, formed under high pressure and temperature, highlighting the beauty and complexity of geological processes.
