Answer:
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.
Similar fossils found on different continents helped geologists determine how the continents used to be connected. Mountain belts marked the boundaries of moving plates, which showed in which direction the different continents drifted. Extrapolating from this information, scientists had a rough idea of how the continents were arranged eons ago.
