Examine the rock cycle (Figure 1) before attempting to answer the following questions. 1. Is the rock cycle a "one-way loop"? In other words, does a rock that starts as an igneous rock have to become a sedimentary rock before it can become a metamorphic rock? Explain. 2. Explain in your own words, using terms from the rock cycle, the path that a rock might take if it starts as an extrusive igneous rock and becomes magma. You may make your path as simple or complex as you choose if it is consistent with the rock cycle. 3.
