We continue this series with 'Questions for any rock face 3: soil; what questions about soil might be asked at any soil exposure?'
Show your pupils the soil at the top of the rock face, if a good profile can be seen in cross section, and ask them these questions:
- How many different soil layers can you see?
- How does rock become changed into topsoil?
- Is this a rich or poor soil? (Generally, the greater the number of growing species there are, the richer the soil)
Many more activities about soils can be found on our website.
