Rocks Questions and Answers

Correct Answer: Option D — Quartzite. Quartzite is correct because it is used as construction aggregate and decorative stone. Quartzite is also associated with a hard metamorphic rock. A further identifying fact is that Quartzite is very resistant to weathering. Another useful fact is that Quartzite is associated with used as construction aggregate and decorative stone. Why the other options are incorrect: Option A — Granite: It is widely used as building and decorative stone and is associated with an intrusive igneous rock; those are the identifying facts of Granite. Option B — Basalt: It is common in oceanic crust and lava plateaus and is associated with an extrusive igneous rock; those are the identifying facts of Basalt. Option C — Pumice: It is used as an abrasive and lightweight aggregate and is associated with a vesicular volcanic rock; those are the identifying facts of Pumice. Exam Takeaway: Link Quartzite with “used as construction aggregate and decorative stone” and “a hard metamorphic rock” for quick revision.

A further identifying fact is that Quartzite is very resistant to weathering. Another useful fact is that Quartzite is associated with used as construction aggregate and decorative stone. Why the other options are incorrect: Option A — Granite: It is coarse-grained with visible crystals and is associated with widely used as building and decorative stone; those are the identifying facts of Granite. Option B — Basalt: It is dark-coloured and fine-grained and is associated with common in oceanic crust and lava plateaus; those are the identifying facts of Basalt. Option D — Pumice: It is so porous that some pieces can float on water and is associated with used as an abrasive and lightweight aggregate; those are the identifying facts of Pumice. Exam Takeaway: Link Quartzite with “very resistant to weathering” and “used as construction aggregate and decorative stone” for quick revision.

Correct Answer: Option B — Quartzite. Quartzite is correct because it is formed from sandstone rich in quartz. Quartzite is also associated with very resistant to weathering. A further identifying fact is that Quartzite is very resistant to weathering. Another useful fact is that Quartzite is associated with used as construction aggregate and decorative stone. Why the other options are incorrect: Option A — Granite: It is formed by slow cooling of magma below the surface and is associated with coarse-grained with visible crystals; those are the identifying facts of Granite. Option C — Basalt: It is formed by rapid cooling of lava at the surface and is associated with dark-coloured and fine-grained; those are the identifying facts of Basalt. Option D — Pumice: It is formed when gas-rich lava cools rapidly and is associated with so porous that some pieces can float on water; those are the identifying facts of Pumice. Exam Takeaway: Link Quartzite with “formed from sandstone rich in quartz” and “very resistant to weathering” for quick revision.
