Why are scientists able to use rocks to be able to find out that a volcano is explosive or nonexplosive?
Explosive and non-explosive eruptions form different types of rock. Explosive eruptions tend to have fragmented rocks composed of cinders, ash, and pumice. Non-explosive eruptions usually produce lava flows, which tend to cool as solid sheets or channels of rock.
