Question
Which of the following statements is true?1 pointContinental crust is more dense than oceanic crustOceanic crust is made mostly of pumice because it is less denseContinental crust is thicker than oceanic crust
Solution
The statement "Continental crust is thicker than oceanic crust" is true.
Here's why:
-
Continental crust is less dense than oceanic crust. The average density of continental crust is about 2.7 g/cm3, while the oceanic crust is about 3.0 g/cm3. So, the first statement is false.
-
Oceanic crust is not made mostly of pumice. It is primarily composed of basalt, a type of igneous rock. Pumice is also an igneous rock, but it's not the main component of oceanic crust. Therefore, the second statement is false.
-
Continental crust is indeed thicker than oceanic crust. The thickness of the continental crust varies from about
