Continental crust choose one: a. is less dense than oceanic crust. b. makes up about 80% of the earth's surface. c. is less buoyant than oceanic crust. d. is thinner than oceanic crust.

A. Continental crust is less dense than oceanic crust.

Explanation:

Earth's crust can be divided into two categories, oceanic and continental. More of the surface is covered by oceanic crust, but because ocean crust is thinner than continental crust, the volume of the latter is significantly greater.

Oceanic crust is also denser than continental crust as it is made up of basaltic rock, whereas it's continental counterpart contains a type of less dense rock called felsic.
