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:

• Formation 1: It is magma that has erupted onto the Earth's surface (extrusion).
• Formation 2: It is magma that cooled and solidified beneath the Earth's surface (intrusion).
• Igneous rock: Both formations are made from magma (Formation 1 - lava, which is magma on the surface; Formation 2 - magma beneath the surface). Igneous rocks form from the cooling and solidification of magma or lava.
• Faults: Faults are fractures in the Earth's crust along which movement has occurred. These are not faults.
• Extrusion vs Intrusion: Formation 1 is an extrusion (lava), Formation 2 is an intrusion (magma that cooled below - surface).

Answer:

Formations 1 and 2 are igneous rock.
