Match each rock in Column I with its corresponding mode of formation or classification in Column II.
- BasaltFine-grained extrusive igneous rock formed by rapid cooling of surface lava
- MarbleNon-foliated metamorphic rock produced by thermal metamorphism of limestone
- CoalOrganically formed sedimentary rock derived from compacted vegetative matter
- SlateFoliated metamorphic rock resulting from low-grade regional metamorphism of shale
Cevap
Basalt matches fine-grained extrusive igneous rock formed by rapid cooling of surface lava; Marble matches non-foliated metamorphic rock produced by thermal metamorphism of limestone; Coal matches organically formed sedimentary rock derived from compacted vegetative matter; Slate matches foliated metamorphic rock resulting from low-grade regional metamorphism of shale.
Each rock is paired strictly with its genesis: Basalt is formed by rapid lava cooling at the surface (extrusive igneous), Marble is created by thermal metamorphism of limestone, Coal originates from compressed organic plant material (sedimentary), and Slate originates from low-grade regional metamorphism of shale.
