answer this
any two from: two parts, inner and outer; outer is liquid, inner is solid; outer core is thicker (2200 km) than inner core (1250 km); radius of core is 3450 k
The average radius of the Earth is 6400 km. Use the information on the diagram to calculate the approximate thickness of the Earth’s crust.
(6400 – (1250 + 2200 + 2900) =) 50 (km);
