Every year at least a 2000 earthquakes explode, each time the earth loses its energy. T herefore in the course of time the inside of the earth will be cold and inert. Please reply. Thanks

The Earth's core is kept warm by radioisotope decay, not some clockwork process that creates earthquakes as it winds down it's mainspring. There's enough radioactive material to keep the core hot well past the point where the Sun will destroy the earth.

The sun's 'life' cycle will cause it to expand out to nearly the orbit of earth when it's hydrogen levels drop past a critical threshold. Being in the suns outer atmosphere will likely drag the Earth out of orbit. That will happen long before the earths magnetic field flickers out.

If you were to turn of the magnetic field permanently now the earth's atmosphere would gradually become thinner because the solar wind would strip away the lighter elements in the upper atmosphere. Most critical among the lost gasses would be hydrogen. The earth would dry out (less H means less H2O) and become a larger version of Mars.

Earthquakes do not use up energy as such. They act to release tension in the surface crust and the friction caused would add heat not remove it.

The mantle is a thick layer of silicate rock that surrounds a dense, predominantly iron core. The outer core is molten liquid and surrounds a solid inner core about the size of the moon. Although at high temperature the pressure keeps it as a solid.

Temperature at the upper boundary of the mantle is about 4,000º F and at the lower end of the boundary the temperature is about 5,800º F.

The inner core, which is slowly solidifying from the inside out as the core cools, may be only about a billion years old.

It is predicted that in about 350 million years the tectonic plates may fuse together again as a super continent and that in that event virtually all volcanoes and earthquakes will cease. In fact all plate tectonics could cease for 100 million years.

It has been suggested that the inner core is cooling faster than scientists thought but do not worry they are talking in terms of hundreds of millions of years!!

There is plenty of heat being generated otherwise the earth would have been cold inside a long time ago. This baffled early scientists trying to date the earth by temperature. The decay of radioactive elements makes heat. This heat means that the earth is cooling down very slowly.

However when the core eventually gets cold the magnetic field will stop. This will no longer protect against the solar wind and our atmosphere will slowly be blown into space just like it happened on Mars.

The main result will be the loss of the magnetic field that is generated by the rotating molten mass. Without the magnetic field, the solar winds will no longer be deflected, and blast the earths atmosphere away gradually, and then the oceans. Mars and the moon are two examples of bodies with little or no magnetic field. Also, your compass won't work, and you'll get lost on the way to Starbucks for your Latte.

Back in the 90s it was announced that the solar system and the earth are part of an electric motor like apparatus. From that fusion reactor, the sun, streams a billion amp current in every direction. This creates heat in the earth in much the same way heat is produced in an electric motor. Thats the simple answer. Do some googling on this subject to find more.

Eventually, billions of years from now, the molten core will cool enough such that the Earth's magnetic field will degrade and eventually cease.

At this point, the solar wind will not be deflected from the Earth and atmosphere and water will eventually be depleted rendering the planet lifeless.

There is a credible theory that at the Earth's core, there is a nuclear-reaction taking place.

As we can't go there to find out, it's a bit difficult to know for certain.

However, on the SURFACE of the Earth, in Africa, there are clear deposits of glass fused into rock, which prove the existence of external nuclear-powered furnaces which burned fiercely many millions of years ago.

Radioactive processes inside the Earth's mantle and core generate as much heat as is lost, so the Earth's inside isn't cooling down.

The Sun will have gone red giant and enveloped the Earth long before it cool!

Dust falling to Earth from Space increases the planet's mass. Gravity keeps the molten rock under pressure. The cooling process you ask about might or might not happen depending on the balance of heat gain/loss and mass gain/loss.
Anyway, ask me in a hundred billion years.

The earth has been here billions of years. It is nothing for us to worry about. Maybe in a few billion years the earth will become a dead planet.
