Correct Answer: Option B — Marble. Marble is correct because it is formed mainly by metamorphism of limestone. Marble is also associated with has interlocking calcite crystals. A further identifying fact is that Marble is has interlocking calcite crystals. Another useful fact is that Marble is associated with used in sculpture and architecture. Why the other options are incorrect: Option A — Slate: It is formed mainly from shale under pressure and heat and is associated with splits into smooth thin sheets; those are the identifying facts of Slate. Option C — Quartzite: It is formed from sandstone rich in quartz and is associated with very resistant to weathering; those are the identifying facts of Quartzite. Option D — 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. Exam Takeaway: Link Marble with “formed mainly by metamorphism of limestone” and “has interlocking calcite crystals” for quick revision.

Correct Answer: Option A — Marble. Marble is correct because it is a metamorphic rock. Marble is also associated with formed mainly by metamorphism of limestone. A further identifying fact is that Marble is has interlocking calcite crystals. Another useful fact is that Marble is associated with used in sculpture and architecture. Why the other options are incorrect: Option B — Slate: It is a low-grade metamorphic rock and is associated with formed mainly from shale under pressure and heat; those are the identifying facts of Slate. Option C — Quartzite: It is a hard metamorphic rock and is associated with formed from sandstone rich in quartz; those are the identifying facts of Quartzite. Option D — Granite: It is an intrusive igneous rock and is associated with formed by slow cooling of magma below the surface; those are the identifying facts of Granite. Exam Takeaway: Link Marble with “a metamorphic rock” and “formed mainly by metamorphism of limestone” for quick revision.

Correct Answer: Option D — Shale. Shale is correct because it is can metamorphose into slate. Shale is also associated with a fine-grained sedimentary rock. A further identifying fact is that Shale is splits into thin layers called fissility. Another useful fact is that Shale is associated with can metamorphose into slate. Why the other options are incorrect: Option A — Marble: It is used in sculpture and architecture and is associated with a metamorphic rock; those are the identifying facts of Marble. Option B — Slate: It is used for roofing and writing boards and is associated with a low-grade metamorphic rock; those are the identifying facts of Slate. Option C — Quartzite: It is used as construction aggregate and decorative stone and is associated with a hard metamorphic rock; those are the identifying facts of Quartzite. Exam Takeaway: Link Shale with “can metamorphose into slate” and “a fine-grained sedimentary rock” for quick revision.
