6. Use your knowledge of the rock cycle and how rocks form (from GEOL 1010) to answer the following
question. Which statement best explains how the gneiss is formed?
There were massive amounts of erosion from an older mountain chain, and the sediments
were deposited in the nearby plain.
Older rocks were buried during a mountain building event and were subjected to increased
amount of pressure and temperature which caused them to metamorphose.
Continental crust was melted and the resulting magma started to rise and intrude into the
Sea level dropped exposing rocks to the elements and resulted in massive amounts of
erosion and weathering.
