Answer 2

Option A, Continental crust is less dense than oceanic crust.

Step-by-step explanation:

Density of continental crust is equal to 2.6 gram /cubic centimeter while the density of oceanic crust is 3.0 gram/cubic centimeter. therefore it can be stated that density of continental crust is lower than density of oceanic crust. The difference is densities is due to the difference in composition of the two crust. Oceanic crust is made up of basalt while continental crust is made up of granite rock.

Hence, option A is correct.
