Question

which two terms apply to continental crust rather than oceanic crust?
less dense
thinner
older in age
darker in color

Explanation:

To determine the terms applying to continental crust (not oceanic):

• Less dense: Continental crust (silicate - rich, like granite) is less dense than oceanic crust (mafic, like basalt).
• Older in age: Continental crust can preserve older rock formations (e.g., ancient cratons), while oceanic crust is recycled at subduction zones, so it’s younger.
• “Thinner” is false (oceanic crust is thinner). “Darker in color” is false (oceanic crust, with more mafic minerals, is darker; continental crust is lighter - colored).

Answer:

A. Less dense, C. Older in age
