Rock+Cycle+Open+Response

MCAS Prep – Rock Cycle Massachusetts has an unusual geologic history. We find highly metamorphosed rocks in the western half of the state, igneous rocks in the central portions of the state, and sedimentary rocks along the eastern shores. We also find that the rocks are oldest to the west and youngest to the east.


 * 1) Explain how the rock cycle could be used to explain the sedimentary rocks in the east.
 * 2) Describe a series of geologic processes that might explain the three rock types, their ages, and their locations.
