Final answer:
To match igneous rock textures with their formation locations: Porphyritic texture suggests an intrusive formation, Aphanitic is associated with extrusive rocks, Phaneritic is also indicative of intrusive igneous rocks (not sedimentary), and Glassy texture pertains to igneous (not metamorphic) rocks.
Step-by-step explanation:
Matching the igneous rock texture with the location where it is likely formed, we have:
- A) Porphyritic - Intrusive: This texture is characterized by larger crystals, known as phenocrysts, set in a finer-grained matrix. Since the porphyritic texture represents a complex cooling history, where the larger crystals have crystallized at depth (intrusive) followed by a phase of quicker cooling, this texture is indicative of an intrusive igneous rock formation.
- B) Aphanitic - Extrusive: Aphanitic texture is fine-grained and is a result of rapid cooling, which is typical of volcanic rocks that have cooled quickly at or near the Earth's surface (extrusive).
- C) Phaneritic - Not Sedimentary: Phaneritic texture has coarse-grained crystals, visible to the nak ed eye, and is characteristic of igneous rocks that have cooled slowly beneath the Earth's surface (intrusive), not sedimentary rocks.
- D) Glassy - Metamorphic: Glassy textures are typical of igneous rocks where the cooling was so rapid that crystal structures could not form, like in obsidian. Metamorphic rocks have been subjected to heat and pressure, resulting in foliated or non-foliated textures, and are not associated with glassy textures.
