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.

Explanation:

1. Analyze each option:

• Option 1: Formation 2 is an intrusion (not extrusion, as extrusion is lava reaching the surface), so this is wrong.
• Option 2: Formation 1 is an extrusion (lava at the surface), not an intrusion (magma below surface), so this is wrong.
• Option 3: Formations 1 and 2 are igneous rock (formed from cooled magma/lava), this is correct. Faults are breaks in rock, not these formations.
• Option 4: Formations 1 (extrusion) and 2 (intrusion) are both igneous rock (formed from magma/lava cooling), so this is correct.

Answer:

Formations 1 and 2 are igneous rock.
