Question 2 • DRHS GA-GSE Earth Systems

An igneous rock has a coarse texture and is dark in color. How else can this rock be accurately described?

Answer
A
small crystals
B
cooled quickly
C
produced from magma
D
formed at Earth’s surface

Explanation

A coarse texture means the rock has large crystals, which form when molten rock cools slowly underground. Dark color often indicates a mafic composition, but it does not mean the rock cooled quickly or formed at the surface. Igneous rock formed from magma beneath Earth’s surface, so “produced from magma” is accurate.
