The Earth's core is a huge metal ball made up of iron and nickel, which is divided into two layers: the inner core and the outer core. The inner core is a solid sphere about a quarter the diameter of the Earth and a temperature of up to 6,000 degrees Celsius, which is equivalent to the surface temperature of the Sun. The outer core is a liquid layer with a thickness of about 2,300 kilometers and a temperature of about 4,000 degrees Celsius. The outer core is the Earth's generator, which generates the Earth's magnetic field by convective motion, which protects the Earth from the solar wind and cosmic rays, while also influencing the Earth's climate and the evolution of life.
Scientists have always been interested in the movement and changes in the Earth's core, and they want to know what would happen to the Earth if the Earth's core stopped turning. To answer this question, they conducted a bold experiment in 2003 in which they used a giant spherical container, filled with liquid sodium, to simulate the Earth's outer core, and then used a motor to drive the container to rotate, creating a magnetic field similar to that of the Earth. Then, abruptly, they turned off the motor, stopped the container from rotating, and observed the change in the magnetic field.
The results of the experiment were shocking, when the container stopped rotating, the magnetic field did not disappear immediately, but began to change rapidly, and a lot of unstable poles appeared, which moved randomly inside the container, causing the strength and direction of the magnetic field to constantly change. Scientists estimate that if this happens on Earth, the Earth's magnetic field will disappear completely within a few hundred years, which will have catastrophic consequences for the planet, such as:
When the magnetic field disappears, the Earth will lose its barrier to the solar wind and cosmic rays, and these energetic particles will destroy the Earth's atmosphere, weakening the Earth's greenhouse effect, causing the Earth's temperature to drop and triggering an ice age.
After the magnetic field disappears, the earth's crust will lose stability, resulting in an increase in the stress of the earth's crust, triggering large-scale plate movements, increasing the cracks in the earth's crust, increasing volcanic activity, and releasing a large amount of dust and gas, further affecting the earth's climate and ecology.
After the magnetic field disappears, the earth's creatures will lose navigation and protection, and many animals that rely on the magnetic field, such as birds, fish, turtles, etc., will not be able to find their way and get lost in the sea or air, unable to return to their breeding or wintering places. At the same time, the solar wind and cosmic rays will cause serious damage to the genes of living things, leading to the mutation and death of living things, and may even trigger the extinction of life.
The Earth's core is the heart of the Earth, which provides the Earth with a magnetic field, crustal stability, and geothermal energy, and if the Earth's core fails, the Earth will face an unprecedented crisis that could lead to the collapse of the Earth's environment and life. Therefore, we should cherish and protect our earth, understand and respect the laws of the earth, and avoid irreversible damage to the earth.
