Question

what rock is this?
conglomerate
granite
marble
basalt
shale
gneiss

Explanation:

• Conglomerate: Consists of rounded gravel - sized particles.
• Granite: Has a coarse - grained texture with visible minerals (usually quartz, feldspar, and mica), which matches the appearance of the rock in the image.
• Marble: Is a metamorphic rock, often with a more crystalline and sometimes banded (if it has impurities) appearance, usually not as coarse - grained with visible distinct mineral grains like granite.
• Basalt: Is fine - grained (aphanitic) as it cools quickly, which is different from the rock in the image.
• Shale: Is a fine - grained sedimentary rock, usually in thin layers (fissile), not matching the texture here.
• Gneiss: Has a banded or foliated appearance (due to metamorphism), which is not seen in the rock.

Answer:

Granite
