Formation of igneous rocks in Ireland | sample answer
... Igneous rock can cause intrusive and extrusive features. Other intrusive example could be sills, dykes, laccoliths and lopoliths, extrusive features can be volcanic plug, volcanic cone and lava plateau. Intrusive features only become known to us when denudation occurs. The rock on the surface must b ...
