20. What step in the rock cycle creates the sediment from which sedimentary rock is formed?
Erosion of igneous and metamorphic (as well as other sedimentary rocks) provides some of the
sediment from which sedimentary rocks form.
21. Describe a pathway through the rock cycle in which magma becomes sedimentary rock.
Magma could cool and harden to become igneous rock, which could erode to become sediment.
The sediment, through compaction and cementation, could become sedimentary rock.
22. Describe two pathways through the rock cycle in which igneous rock can become
metamorphic rock.
Igneous rock can undergo high temperature and pressure and turn into metamorphic
rock. Or, igneous rock can undergo erosion to form sediments that get compacted and
cemented to form sedimentary rock. Then the sedimentary rock can undergo high
temperature and pressure to become metamorphic rock.
