A metamorphic rock could become magma as a result of a collision involving an ocean plate. During
subduction, any rock carried on the plate would return to the mantle and melt, forming magma.

72. ANS:
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.

ESSAY
74. ANS:
The color of a mineral is an easily observed property. However, many minerals occur in a variety of colors,
so few minerals can be identified based only on their color.

75. ANS:
A mineral must occur naturally, be inorganic, be a solid, have a crystal structure, and have a definite
chemical composition. Coal is formed from the remains of ancient plants and therefore is not inorganic. Glass
is a human-made material, so it does not occur naturally.
