What if there are no mountains?

What if there are no mountains?

The quick answer is that we would have had to wait several thousand years for the mountains to reappear. Mountains are a natural consequence of the movement of tectonic plates. As erosion slowly removes mountains, plates are constantly being replenished. The truth is that the age of the oldest mountains on earth is never comparable to Earth.

Suppose, however, that the forces influencing the movement of tectonic plates did not exist. One of these forces is gravity, but without gravity, there will be no ground at all. We can overlook gravity, focusing on another force, the convection of the Earth's mantle.

To illustrate the idea here, we point out that the earth's scarf is the geological layer that lies beneath the Earth's crust, which is a liquid mineral (it is the source of lava). This layer has a movement similar to that of ocean currents. When the liquid metal cools down, its density is relatively low, and it moves towards the surface of the earth. When it touches the surface of the earth from below, the liquid solidifies and increases in density. The general result of this movement is the movement of tectonic plates and collision or spacing. 

The collision leads to the emergence of high-rise chains such as the Himalayas and the divergence between the Arab and African plates has led to the development of the Tihama Mountains.

But what if there was no heat load of the scarf and no tectonic movements? There will be several key results. The first is the nature of the sequence of ideas lack of mountains. In fact, Australia is a geologically inert mass of land. The renewal of mountains has been rare for millions of years. The soil is therefore not regenerated by erosion or by volcanic ash, which contains minerals that are beneficial to plants. As a result, Australia's soil is neither vital nor generally suitable for agriculture and the continent is mostly deserted.

Another consequence is the disruption of the geological CO2 cycle. Geological activity is an important factor in stabilizing carbon dioxide in the earth through its interaction with limestone, and by the formation of kerogens in fossil fuels. This cycle is very slow, of course, but of great importance in the balance of carbon dioxide in the atmosphere.

The absence of mountains will end life as we know it on this planet. And if life still exists, the peach culture will be quite different from what we know. The movement of dissolved metals in the mantle generates a geomagnetic field, without the compass could not be invented. The absence of mountains will greatly reduce the prospecting of minerals because prospecting will inevitably be drilled vertically into the ground with tools that need the same minerals found in the earth.
