What would happen if the earths core were to solidify?
Earth’s liquid core is what is believed to create the earth’s magnetic field. No magnetic field means no poles. Without that magnetic field, which acts as a shield, the solar wind would blow away most of the earth’s atmosphere and things that like oxygen would be kaput. Bad news for humans. Scientists can see what happens when they check other planets that are smaller, like mars, whose core has cooled to a solid and caused the magnetic field (shield) to disappear. Information on our core (both inner and outer) The outer core of the Earth is a liquid layer composed of iron and nickel above the solid inner core. It comprises approximately 22.37% of Earth’s mass. Its outer boundary lies approximately 2,890 km (1,800 mi) beneath the Earth’s surface, below the mantle. The temperature of the outer core ranges from 4400 °C in the outer regions to 6100 °C near the inner core. Eddy currents in the nickel iron fluid of the outer core are believed to influence the magnetic field of the Earth. It
