2
Q
Explain how Slate is formed
A
Slate is formed by shale
Shale undergoes heat and pressure
Which causes shale to change into Slate
3
Q
Why is slate a better material than shale
A

4
Q
Explain how Marble is formed
A
- Marble is made out of limestone
- Limestone undergoes heat and pressure
- Which causes limestone to change into marble
5
