Question

(ii) The crust is made up of rock and the mental is also made up of rocks. If this is so
then why the crust is floating on the mantle?​

Answer 1

Answer:

Earth's Crust

“Crust” describes the outermost shell of a terrestrial planet. Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth's crust is informed by plate tectonics.

Answer 2

Answer:

• The continental and oceanic crusts sit on a thick layer of solid rock known as the mantle.

Explanation:

• They drift because they are sitting on a layer of solid rock (the upper mantle or "asthenosphere") that is weak and ductile enough that it can flow very slowly under heat convection, somewhat like a liquid.
