Which of the following igneous rocks would be formed by the slowest cooling?
A) coarse granite
B) medium-grained granite
C) fine-grained granite
D) volcanic glass
E) there is not enough information to tell
Volcanic Glass
A type of rock formed from the rapid cooling of lava without crystallization, producing a natural glass.
Coarse Granite
A type of granite rock characterized by large grains or crystals, indicative of slow cooling beneath the Earth's surface.
Cooling
Cooling refers to the process of losing heat, in the geological context often relating to the solidification of magma into igneous rock.
