Question

as labeled in this diagram, in which layer are you most likely to find a green, crystalline igneous rock called peridotite? a b c d

Explanation:

Peridotite is associated with the Earth's mantle. In the diagram, layer C (assuming standard Earth - layer diagrams where C is the mantle) is the mantle. The mantle is composed of ultramafic rocks like peridotite, which is a green, crystalline igneous rock. Layers A and B are likely the core (inner and outer), and D is the crust, which does not typically have peridotite in large - scale, crystalline form as found in the mantle.

Answer:

C
