The melting temperature would drop. If it dropped to a point below the in-situ temperature, melting of the inner core would occur.
it would decay
typhoons form when the following conditions are met Their is a low pressure area The water is warm (around 80'F) the low pressure and warm water allow the water to evaporate and condense very rapidly and the earths spin causes the typhoon to spin. However this does not happen around the equator as the force of the earths rotation is not strong enough. This is a good thing as if it did not happen like this the areas there would have an endless hurricane season
Sinking air would add air to the surface, raising the pressure.
It would undergo metamorphism, if the heat and pressure are sufficient.
it would not be good
split
It would harden and then become hard rock.
Humans and any living creatures would die and no one would survive.
Venus. Its has a very thick atmosphere of Carbon dioxide. Its average surface pressure is a crushing 93 bar, or 93 times that of Earths.
the inner core
If mountains weren't being formed there would be a lot more earthquakes. This would be due to the build up of pressure at the fault lines.
The temperature would be different on Earth.
it would become to cold
The length of the day
we would die
You would be incinerated by the heat. totally legit.
The air pressure would reduce.
