What fraction of the thickness of the thickest continental crust is the thickness of the oceanic crust? Give your answer as a reduced fraction.

• Science -

What thicknesses are you using for these crusts?

• Science -

Continental crust is 100km
Oceanic crust is 5km

• Science -

5/100 = 1/20

• Science -

5km/100 is equal to 1/20 because you dived 5km/100km by 5 which gives you 1/20
