The thickness of earth’s crust depends upon
a.
whether it is continental or oceanic
b.
the temperature of the outer core
c.
how volcanically active the region is
d.
all of the above

The best and most correct answer among the choices provided by the question is the first choice "whether it is continental or oceanic"

The oceanic crust is 5 km (3 mi) to 10 km (6 mi) thick and is composed primarily of basalt, diabase, and gabbro. The continental crust is typically from 30 km (20 mi) to 50 km (30 mi) thick and is mostly composed of slightly less dense rocks than those of the oceanic crust.

I hope my answer has come to your help. God bless and have a nice day ahead!

Just do the math, then think
