Question

1. metamorphic rock forms as a result of changes in ____ and ____ in earths interior.
2. sep evaluate evidence an igneous rock contains large crystals of quartz, feldspar, and hornblende. how did the rock most likely form?

Explanation:

For question 11: Metamorphic rocks form when existing rocks are altered by conditions deep within Earth that change their structure and mineral composition. The key driving forces are increased temperature and pressure.
For question 12: Igneous rocks with large crystals form from magma that cools slowly over time, allowing enough time for mineral grains to grow to a large size. This slow cooling occurs underground, not at the surface where cooling is rapid.

Answer:

1. temperature; pressure
2. This igneous rock most likely formed from magma that cooled slowly beneath Earth's surface, giving enough time for large quartz, feldspar, and hornblende crystals to grow.
