Correct statements: 1, 2, 3, and 4. Incorrect: 5.

Brief explanations:
- 1 True — Magma is molten rock (rock that has melted) beneath the surface.

- 3 True — Igneous rocks form by cooling and solidification of molten material (magma or lava).
- 4 True — Lots of igneous rock forms near plate boundaries (mid‑ocean ridges, subduction zones) and at hotspots.
- 5 False — Most igneous rock is formed below the surface, not on it.
