Earth Core Cooling | This is what will happen when the Earth’s core is cold?

Earth core cooling

Earth Core Cooling

Earth core cooling very fast. Earth’s core freezes and cools at a rate of 1000 tons per second or 100,000 kg (220 462 lbs) in other words more than 31 billion tons of the core freezes every year. Due to the heat that the Earth emits into space, the seed of the Earth’s core is petrified and rises by a millimeter each year.

Every second, the Sun radiates into space and towards our planet a stream of a million tons of protons and electrons: this is called the solar wind. These particles are intercepted by the Van Allen belt, the earth’s magnetic field. This one, which spans more than 70,000 kilometers, is produced by the iron and nickel that make up the Earth’s core. This core consists of a solid, seed, 2,800 kilometers in diameter, surrounded by a liquid layer 2,000 kilometers thick. This continuous stirring of the molten metal layer creates a magnetic field.

The earth is cooling and the core is hardening

Problem: cooling of the Earth’s core has the effect of solidifying the liquid layer on the surface of the seed, at a rate of 10,000 tonnes per second. The seed grows several tens of millimeters per year (that is, 500 kilometers per billion years). When, in a few billion years, the seeds will occupy most of the core, the Earth’s magnetic field will be extinguished. Losing this shield, the Earth will be illuminated by the solar wind.

The planet’s interior properties and the strong stellar irradiation might lead to a hemispheric tectonic regime. © University of Bern [Universität Bern](CH) Credit: Thibaut Roger.
