We are very, very sure.

Who is we?
I've never even attempted to verify any of those things and I don't know anyone who has.
What experiments can I perform to verify the dynamo model is correct with 100% certainty?

Why do you think you're ignorance is some kind of hard boundary for the rest of the human race you monumental fucking retard.

>>11100421
There is a way. Seismographs that trace the shock waves produced by tectonic movements detect a discontinuity inside the Earth's internal structure that signals there is a change in the elements it's made of or the state of matter.

The discontinuities are;

Conrad Discontinuity: Transition zone between SIAL and SIMA.

Mohorovicic Discontinuity: Transition zone between the Crust and Mantle.

Repiti Discontinuity: Transition zone between Outer mantle and Inner mantle.

Gutenberg Discontinuity: Transition zone between Mantle and Core.

Lehman Discontinuity: Transition zone between Outer core and Inner core.

Or I could just post ten times as much.

Yes.

That's some convincing evidence, I would hazard to guess.
I can't think of any reason in particular why the dynamo model would be incorrect.
I mainly replied to OP because I wanted him to answer these questions for himself, you know.. the socratic method.
Thanks for contributing, though.
I'm curious what OP believes could constitute as an alternate model with even a 1% probability of existence, and his reasons for thinking that.

>>11100454
I'm the OP

This is what I've learned at the uni but most of my teachers still say that the tectonic plates are a theory, they never say it's a fact. It's like if it was evolution. Most of the scientific community take it as a fact but it's still just a theory.

But is there any other differing view about it?

>>11100459
Newtonian mechanics, relativity, genetic inheritance, chemical bonds, etc are all "just theories"

>>11100459
You're studying stem science at university and you don't know about theories?
Bruv in science a theory is not a guess that could be wrong, it is a reliable conceptual model which is supported by all available evidence.

For example, these strata marked by the discontinuities in the seismological readings are predicted by the theoretical model (theory for short).
The theory doesn't come from interpreting the data, the theory makes predictions that are either confirmed or denied by the data. A theory is good if the data confirms its predictions.
Welcome to science.

Put it this way, when I was a kid the Earth had a solid iron core surrounded by a liquid mantle. Now the core is liquid rock. This shit is all guesswork based on measurements of temperature, magnetism, etc.

Also the Nimitz Incident points to an underground "vril" civilization that would need extensive caverns at least and quite possibly a hollow interior to the planet.

>>11100516
I know what a theory is. I just was curious about any other theories about the internal structure of Earth

>>11100538
There are no other working theories.

>>11100536
The outter core is liquid iron and nickel alloy, the inner core is exactly the same thing as the outter core but it's solid because of the pressure

>>11100536

The core is still solid iron surrounded by liquid iron you schizoid boomer.

Ah now the motivation for this post is revealed.
>Vril
Ah yes, I too have watched season 2 of ancient aliens on Netflix.

>>11100628
Yeah yeah hybrid human are sure retarded.

>>11100401
Hollow earth. Don't let anyone tell your otherwise and make your own search. You'll find why (((they))) don't want to show you the truth.

>>11100453
double yes

Nah. We're all going to die when the poles flip.
