Question

This diagram shows rock formations forming.



Which statement describes one or both formations?

Formation 2 is an extrusion.
Formation 1 is an intrusion.
Formations 1 and 2 are faults.
Formations 1 and 2 are igneous rock.

Answer 1

Based on the descriptions provided, the correct statements would be:

- Formation 2 is an extrusion. (This means that it is a volcanic rock that formed from lava that cooled on the Earth's surface.)
- Formation 1 is an intrusion. (This indicates that it is an igneous rock that formed from magma that cooled and solidified beneath the Earth's surface.)

Therefore, the statements you mentioned are likely correct: Formation 2 is an extrusion, and Formation 1 is an intrusion. The statements regarding faults or both formations being igneous rock would require additional context to confirm their accuracy. However, since extrusions and intrusions are both types of igneous rock, it can be said that both formations are indeed igneous rock.

So, the best choices would be:
- Formation 2 is an extrusion.
- Formation 1 is an intrusion.
- Formations 1 and 2 are igneous rock.
