This diagram shows rock formations forming.

which statements describe formations 1 and 2? check all that apply.

formation 2 is an intrusion.

formation 1 is an extrusion.

formations 1 and 2 are faults.

formations 1 and 2 are igneous rock.

formations 1 and 2 are the same age as the surrounding layers.

The correct answers are:

- Formation 2 is an intrusion;

- Formation 1 in an extrusion;

- Formations 1 and 2 are igneous rocks;

The formation one on this image is an extrusion, and the reason why it is an extrusion is that it has come out on the surface. The formation two on this image is an intrusion, and the reason why it is an intrusion is that it has formed deep into the ground.

Both of the formations will produce igneous rocks. The formation one will produce extrusive igneous rocks that will have very small crystals because of the quick cooling off of the magma. The formation two will produce intrusive igneous rocks that will have larger crystals because of the slower cooling off of the magma.
