Both Jenny and Jack are correct.
Explanation:
According to the principle of superposition, both Jenny and Jack are perfectly correct.
The principle of superposition states that the oldest bed is at the bottom and the youngest is on top in an undeformed sequence of rock strata.
From this principle we can see that the sequence of the bed is:
- soil Youngest rock layer
- loam
- sand and gravel
- loam
- clay
- impermeable rock (limestone) Oldest rock layer
We can see that truly the clay is older than the sand and gravel according to Jenny.
The limestone is also older than loam according to Jack.
