Is Hollow Earth theory true ?

Question

I found many people believe in hollow earth theory
and they think that it's true
is it really true ?

Answer 1

No, the Earth is not hollow.  It consists of 4 main layers:

1. A solid outer crust that forms the earth's surface - it's where we live and is only about 10 miles thick
2. The mantle, consisting of superheated rock.  The mantle is about 2000 miles thick and makes up most of the Earth's mass
3. The outer core consisting of molten rock and metals
4. The inner core consisting of solid iron and nickel
