1. Which type of rock forms from:
   
   
   1. intense heat and pressure?
   metamorphic rock
   
   
   2. compacted and cemented fragments of other rock?
   sedimentary rock
   
   
   3. magma or lava that cools and hardens?
   igneous rock
   
   
2. Does all rock have to follow a sequential circular path as it goes through the rock cycle? Explain.
Rock does not have to follow a sequential circular path as it goes through the rock cycle. Various physical processes affect the formation of different types of rock. For example, igneous rock, instead of transforming into sedimentary rock (by weathering) may instead be transformed by intense heat and pressure into metamorphic rock.
