If the core of Earth gets cool down people will too

Our core is very hot. If it was on a cold, dark morning in midwinter, you might only feel cold, but beneath the surface of the earth, there is a hot center that is made almost entirely of metal.

The core is mainly composed of an iron-nickel alloy, and the liquid of outer core acts as a buffer between the core and the lower mantle (a layer of magma and molten rock).

The core is a solid, iron-rich ball that is approximately 750 miles (1,207 kilometers) thick. It is also the hottest place on Earth, with a maximum temperature of 11,000 degrees Fahrenheit (6093 degrees Celsius), according to National Geographic.

what happens if the earth core cooled down

As the discussion on the harmful effects of global warming becomes fiercer, you may think that the Earth’s core will cool down a bit, but in fact, we need to keep the core state hot so that we can protect the Earth from the potentially harmful solar wind and Interstellar debris damage.

The core of the earth is as warm as the surface of the sun. Since about 4.5 billion years ago, the core has maintained this temperature, while the critical period when the planet was originally composed of gas and particles.

Gravity causes iron and other heavier matter to sink to the middle of the earth, while lighter materials such as air and water rise to the earth’s crust.

The mass of matter at the center of the earth is so large that the gravity at the outer core is three times that of the earth’s surface. It still retains some of the original heat, and the heat generated by the gravitational friction when the heavier matter approaches to the center.

The Core continuously growing at a rate of about 1 centimeter per 1000 years, and as it expands it will gain more heat. Moreover, decaying radioactive isotope also adds heat to the core as it emits radiation from the mantle. Also, the power companies trying to extract radiant heat from the earth’s crust, and then use it to heat the water, which becomes steam to make the turbine generate electricity.

What happens if the earth core cooled down?

Coming to the point, If the core is completely cooled, the earth will become a cold and lifeless planet. At the same time, it will gradually become dark.

Once the core has cooled down, the human world will also fall into darkness.

Core cooling also causes us to lose the magnetic field that surrounds the Earth. These magnetic fields are formed by the heat generated by the Earth’s core. This barrier protects the Earth from the radiation of the universe. This layer of protection shield is generated by the convection process caused by the constant movement of iron.

Just like the Earth itself, the Earth’s core is also constantly rotating – some scientists believe that it rotates even faster than the rest of the Earth. Friction causes the kinetic energy to be converted into electrical energy and magnetic energy that can form a magnetic field; so that harmful charged particles emitted by the sun are deflected toward the north and south poles.

It remains unclear how much depletion of a magnetic field will have an impact on life on Earth.

Some people say cooling down may increase the radiation waves, which will make the earth overheated and uninhabitable. Others also pointed out that the dramatic increase in sunlight may lead to an increase in the incidence of cancer. There are more observers who say that we may encounter solar winds that sweep through everything and may be as strong as those solar winds that sweep Mars, Venus, and all its oceans, lakes, and rivers.

To be sure, it’s best not to figure out what it means to lose the magnetic field.
