Read this excerpt from "Mars: Landscape of the Red

Planet."

What is the best description of the geology of Mars?

Abc

Mars's complexity goes well beyond its surface. Much of the

red planet was formed from volcanic material. The southern

part of Mars appears to have formed from volcanic activity.

This part of Mars has an ancient crust that is mainly mafic in

composition and contains high levels of iron and

magnesium. The lowlands in the northern parts of Mars are

younger and consist mostly of felsic rock, which is high in

potassium, silicon, and aluminum.

A. It is diverse, and different parts formed at different times.

B. It is like Earth, with volcanoes, ocean valleys, and thick

crust.

C. It is simple, containing the same type of material and

appearance everywhere.

D. It is like the moon, because it is made of rock inside and

on the surface.
