The earth's core and under the solid outer skin, the crust, hot liquid magma is there which some times get out through active volcanoes and the red hot flowing liquid called lava. What would happen if hot magma transformed into solid rocks?

By the time this happens naturally it is likely that the Sun would have expanded to a red giant and destroyed the earth anyway.
Were it to happen overnight by some supernatural cause then our main problem would be the loss of the magnetic field created by the liquid core. This Magnetic field helps protect life on Earth from solar radiation. Without it much life on Earth may find its continuation untenable

1. The pressure increases as you go closer to the center. Pressure is accompanied by heat, and thus the outer core is molten magma. However, as it gets closer and closer the pressure becomes more intense and at a stage - the inner core - it becomes solid, extremely hot, metal. 2. No, our planet is a planet, and stars are stars. They are quite different in both composition and properties. Our planet has not and never will follow the stages in life a star does. (About Earth sprouting life: Earth has a natural balance - being not too close and not too far from the sun to create life.) 3. This question is a little confusing. If you're referring to your first question - then yes. Except, the pressure of being under the entire earth is a lot more than that of being under an ocean of water. 4. Nobody can really test that, because drilling to the core is impossible as of yet. I don't believe we can even drill past the mantle (after the crust) since - it's liquid.

That soft squidgy bit in the middle also generates our magnetic fields which do quite a good job of deflecting some of the solar radiation that's banging around up there.
Without those Fields I'm afraid our atmosphere will just get stripped away
Mars has a solid core so I suppose we could end up a bit like that.
By the way with all that stuff just flowing around down there, we're long over due for a polar shift when the north and south pole decide they want to be somewhere else. Which promises to be a pretty exciting day.

That is not apt to happen for a long long time because there are almost unlimited heavy atoms within the earth's interior that are still undergoing natural radioactive decay which constantly supplies fresh heat energy with no place to go. This likely drives the techtonic plates of the earth's crust and powers all the volcanoes that vent excess heat energy.

Most of the predictions were correct except the magnetic field. It will change but will be there since the iron core is solid and it will continue to be there and it will be rotating with earth. So the magnetic field will still be there. We will become inactive planet. So we may become little colder I don't know how much colder. Also i don't know whether the greenhouse effect will compensate for that loss of heat. Some one should Analise this with real data.

Just look at Mars, and there is your answer. No more plate tectonics and no more magnetic fields.
Mars is half the diameter so 1/8 the volume of earth. A smaller body looses heat faster, so Mars got cold first.
By the way, it's magma underground, lava when erupted.

Not alot but there would be no more volcanoes. Plate tectonics would stop but that is so gradual that nobody would notice.
The magnetic field would slowly fade but again it would be so slow that it would be almost undetectable (you can't change a magnetic field quickly).
No change to the atmosphere but more radiation in earth orbit although that would not get to the ground. Any radiation 'feeble' enough to be deflected by the earths magnetic field cannot get through the atmosphere.

Earth most likely to lose it grativity power. Well, get your own imagination if that happen. One for sure, we won't survive. (when I said gravity it not only mean the magnet that make you be able to stand on your feet in the ground, but also what makes the earth in its position in the galaxy).

1. Volcano's would cease to exist
2. Plate techtonic movement would cease to exist and the land would be worn to beneath the sea
3. The earths magnetic field would disappear
3a we would lose protection from solar radiation due to 3
the atmosphere would start to be blown away due to 3a
4 due to 3a and 3b we would all die!

One thing that will happen is that the earth will go off its axis, and when that happens, just about everything else you can imagine will follow.
