Answer:
b less dense and thicker under the continents than under the oceans
Explanation:
- <em>Oceanic crust </em>is found under the ocean, it's about 6 kilometers thick and is destroyed in subduction zones just like the continental crust. It's composed of several layers and it differs from continental crust because it's thinner, denser, younger and with a different chemical composition (olivine, pyroxene, and amphibole).
- <em>Continental crust</em> is thicker (100 kilometers) and less dense than oceanic crust, it resists subduction and its age is 30 times the average of the ocean's age.
Considering this information we can conclude that the correct asnwer is: b less dense and thicker under the continents than under the oceans.
I hope you find this information useful and interesting! Good luck!
