I'll answer these in order to the best of my abilities.
Neither Columbus or megellan discovered the earth to be round.
The earth's magnetic field has its ends at the poles. It comes out vertically here and curves over to the other pole.
He found his bearing on the edge and followed it.
How does this relate to the roundness or flatness of the earth?
The sun only looks bigger because you can use the trees, mountains, etc as a reference. The same goes for the moon.
The atmosphere filters the light because there is more for the light to pass through.
The earth has a slight wobble which causes certain bearings to shift.
Magnetometers.
The earth's tilt is the same as it rotates and revolves. The angle is different in relation to the sun in different seasons.
The young earth was hit by a mars-sized object a few billion years ago, causing a tilt. The earth's tilt isnt affectad by the sun's gravity because the earth is a sphere.
Check out General Relativity.
One AU is the distance from the earth to the sun.
See general relativity once again.
It rotates seperately from the rest of the earth, causing a dynamo effect. We can use seismicdata to find out what the layers are.
Quasars, supernovas, Gamma ray bursts, Black hole jets, pulsars.
Quasars are powered by nuclear fusion.
How is this question relevant?
See above.
Planets form when dust clumps together. This continues until it gets really big. These giant balls of rock compress into denser balls of rock and so on, until a planet forms. (gasses are pulled in, comets hit the surface and make water, etc.)
Global warming periods can cause fresh water to disrupt the oceanic currents, cooling the planet.
No.
It's just easier to make in nature.
There's a test, but I doubt it's simple.
I don't think it would be the standard model if it didn't.
The Big Bang.
Science tries to promote basic fact unless it is proven wrong.
