Sample Questions Exam #1
1. Why do we use composition and texture as the
primary basis for classification of rocks? Cite a
specific example.
2. How do interactions between the solid earth system
and the hydrological system led to sedimentary
rocks?
3. Explain why silicates are the most abundant mineral
class and why there is such a diversity in silicate
mineral structure types.
4. Describe how magma forms at a convergent plate
boundary and what types of igneous rocks are likely
to be formed (a diagram would be very useful).

Sample Questions Exam #1
5. Describe Bowen’s reaction series and the
relationship between it and the classification of
common igneous rocks (a diagram would be very
useful).
6. Describe the rock cycle and explain the basis for the
different major rock families (a diagram would be
very useful).
7. Describe the relationship between magma type,
plate tectonic setting and mode of emplacement of
igneous rocks.
8. Compare and contrast metamorphism and
weathering; how are they the different and how are
they similar? Cite specific examples.
