Answer :

Final answer:

The Earth is an oblate spheroid, the Equator divides the planet, and a journey to the center is impossible due to extreme conditions.


Explanation:

Yes, we can affirm that the Earth is an oblate spheroid, slightly flattened at the poles and bulging at the equator due to its rotation. The shape of the Earth has been proven through various methods including observations of ships disappearing over the horizon, the curved shadow on the Moon during a lunar eclipse, the shape of Earth's shadow on the Moon during a lunar eclipse, and images of Earth from space.

The line imaginary that divides the planet into the hemispheres north and south is called the Equator.

To reach the center of the Earth, as depicted in Julio Verne's novel, is impossible due to extreme heat, pressure, and the molten nature of the Earth's core. The sheer depth and the intense conditions make such a journey unfeasible.
