Crust describes the outermost shell of a terrestrial planet. Earth’s crust is relatively thin, just 40-kilometers (25-miles) deep. Earth's crust can be divided into two types: continental and oceanic. How do these two types of crust differ? All BUT ONE could apply.

"Crust" refers to a

terrestrial planet's outermost surface.

In general, the Earth's crust is divided into

older, thicker continental crust and younger, denser oceanic crust.

The thin, 40-kilometer (25-mile) deep crust of our planet — just

1 per cent of Earth's mass — contains all known universe existence.

Explanation:

Continental crust is thicker, 22 miles (35 km) on average and less dense than oceanic crust, which accounts for its mean surface elevation of about 3 miles (4.8 km) above that of the ocean floor (Archimedes’ principle). Continental crust is more complex than oceanic crust…
