If gravitational force is maximum on Earth's surface, if we are able to reach the centre of Earth alive, will we come upwards automatically?
That's really interesting. Is there anything else you can tell me about the structure of the Earth?
The Earth has different layers, starting with the solid outer crust, which is made up of tectonic plates. Below that is the mantle, which is mostly solid but has pockets of magma. Finally, at the center of the Earth is the core, which is made up of two parts: the outer liquid core and the inner solid core.
