Question

question 1 some igneous rock forms from magma that cools slowly within earths crust. briefly describe the most likely crystallization and texture of the rock. question 2 a scientist shows you a sample of rock called gabbro. the scientist explains that gabbro is an intrusive mafic igneous rock. explain what this means.

Explanation:

For Question 1: Slow - cooling magma within the Earth's crust allows ample time for mineral crystals to grow. This results in large, well - formed crystals and a coarse - grained texture.
For Question 2: "Intrusive" means the magma cooled and solidified below the Earth's surface. "Mafic" refers to rocks rich in magnesium and iron, typically dark - colored and having a high density. Gabbro is a common example of such a rock.

Answer:

Question 1: Slow cooling leads to large crystals and a coarse - grained texture.
Question 2: Intrusive means it formed below the surface; mafic means it is rich in magnesium and iron.
