Question

what is the approximate thickness of earths crust? 400-600 km 100-200 km 200-400 km 5-70 km

Explanation:

The Earth's crust varies in thickness. Oceanic crust is thinner, around 5 - 10 km, and continental crust is thicker, up to about 70 km. So the approximate thickness range is 5 - 70 km.

Answer:

5 - 70 km
