Is that rock sedimentary or igneous?

The new ELI today is 'Questions for any rock face 4: rock group (sedimentary or igneous)'. This activity provides teachers and leaders of field trips with questions to ask when looking at any rock exposure. The answers are used to distinguish between exposures of sedimentary and igneous rocks using simple criteria. (For simplicity, we are leaving metamorphic rocks until later in this ‘Questions for any rock face’ series).
