Quiz Answer Key and Fun Facts

1. Is sandstone igneous, sedimentary or metamorphic?

Answer: Sedimentary

Sandstone is formed when sand particles are compacted, usually under water.

2. Is limestone igneous, sedimentary or metamorphic?

Answer: Sedimentary

Limestone is formed under water from the shells and skeletons of marine animals. Limestone caves, with their stalagmites and stalactites, are formed when water carrying dissolved limestone evaporates, leaving the re-formed limestone.

3. Is basalt igneous, sedimentary or metamorphic?

Answer: Igneous

Basalt is formed when a volcano erupts, pouring lava down its slopes. The lava cools quickly in air, forming fine-grained basalt.

4. Is slate igneous, sedimentary or metamorphic?

Answer: Metamorphic

Slate is formed when shale, a sedimentary rock, is subjected to heat and pressure, changing its structure to the harder slate.

5. Is marble igneous, sedimentary or metamorphic?

Answer: Metamorphic

Marble is formed when limestone is subjected to heat and/or pressure. It is a beautiful building material and used in sculpture.

6. Is granite igneous, sedimentary or metamorphic?

Answer: Igneous

Granite is formed when molten rock (called magma) cools slowly underground, sometimes in the vent of a volcano. After many years, the surrounding softer material is eroded away, leaving exposed volcanic 'plugs' of granite.

7. Is quartzite igneous, sedimentary or metamorphic?

Answer: Metamorphic

Quartzite is formed when sandstone is subjected to heat and/or pressure, forming a harder rock.

8. Is conglomerate igneous, sedimentary or metamorphic?

Answer: Sedimentary

When a mixture of pebbles, sand and mud is washed out to sea, it settles on the sea bed and is compacted over time into conglomerate. Over long periods of time, forces within the Earth's crust may mean this rock ends up being above water.

9. Is shale igneous, sedimentary or metamorphic?

Answer: Sedimentary

Shale, or mudstone, is a fine-grained sedimentary rock formed when mud is compacted and solidified. It may become the metamorphic rock slate.

10. Is gneiss igneous, sedimentary or metamorphic?

Answer: Metamorphic

A 'nice' one to finish with, gneiss is formed when granite is subjected to heat and/or pressure.
