ACTIVITY 5: Rock can follow many different pathways through rock cycle. Read the example below. Then
answer the questions that follow.
Pathway 1
Between New Zealand and South America, at the bottom of the Pacific Ocean, molten material from
the mantle erupts from the mid-range ridge. As the material comes into contact with the very cold
ocean water, it cools quickly to become a rock. Over time, this rock ever slowly moves away from
the mid-range ocean ridge, as seafloor spreading makes changes in the ocean floor. About 200 million
years later, the rock is subducted at a deep ocean trench. As the rock moves downward, it melts to
become part of the mantle. Eventually this melted material moves back up through the mid-ocean
ridge to become rock again.

2. Make a flowchart that describes what occurs in Pathway 1.
