Then our hours on day and night would be alot longer
If the convection currents in the earth's mantle slowed down then the mantle would slow down. Eventually, the mantle would stop all movement.
Nothing realy really. If it sped up it would spin faster and make shorter days and would revolve around the sun faster. If it slowed down it would spin slower making longer days and it would revolve around the sun slower.
level of mercury fall down
There are thousands of reasons this could happen and not diagnoiseable unlesss it is doing it when the mechanic has it.
If the Earth were to slow down, the length of a day would increase, causing changes in weather patterns, ocean currents, and ecosystems. This could lead to disruptions in agriculture, navigation, and communication systems.
The past participle of "slow down" is "slowed down."
The past tense of "slow down" is "slowed down."
If that were the only change, the seasons would simply be longer in duration, extending to about one quarter of the orbital period each.
If the Earth's rotation slowed down, our we would have less gravity, and when we have less gravity we have things floating around for long nights and long days (also due to the planet slowing down). This can lead to many dis functions and could cause the appearance of anti-matter.
If the rate of mutation slowed down, it could lead to decreased genetic diversity in a population, making it more vulnerable to environmental changes or diseases. This could ultimately reduce the ability of a species to adapt and evolve over time, potentially increasing their risk of extinction.
International trade slowed down as a result of the Hawley-Smoot tariff.
