Earth’s inner core pose threat to humanity ?!
An Earth-sized planet’s core would not stop rotating because it is constantly in motion due to the planet’s rotation. The motion of the core is caused by the convection of the liquid outer core, which is driven by heat from the decay of radioactive elements. This process, known as geodynamo, is responsible for generating the Earth’s magnetic field. However, if the planet stops rotating, the core rotation would slow down, but not come to a complete stop.
If the rotation of the Earth’s core were to slow down significantly, it could potentially have significant effects on the planet. The Earth’s magnetic field is generated by the motion of the liquid iron in the core, and a slowing of this motion could lead to a weakening of the magnetic field. This could have a number of effects, including increased exposure to solar radiation, increased auroral activity, and possible disruptions to satellite and power grid operations.
Slowing of the core rotation could also affect the planet’s climate. The Earth’s rotation helps to distribute heat around the planet, and a slowing of this rotation could lead to changes in atmospheric circulation patterns, which could in turn affect weather patterns and climate.
Earth’s core rotation is not something that can be stopped or controlled by human means, so the potential for this to happen is very low.
