How does the inner core affect all of earth's other layers?

Because of its rotation, the inner core of Earth is the cause of its magnetic field. This magnetic field helps protect the surface of the Earth from cosmic rays and other space-related particles. Human life could never have developed without this protection. The heat also accounts for most of the geological activity on Earth, including continent drift, and the magma associated with volcanic activity.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
