OUR WORLD CAN BE DEADLY


Our world is made up four layers, namely the inner core, outer core, mantle, and the crust. The earth’s lithosphere comprises the crust, where the living organisms can be found. The earth’s crust is not entirely a solid state. It is made of tectonic plates attached together side by side. The side of one tectonic plate is partly on top of another tectonic plate. That is how the earth’s crust looks like. The movements of the tectonic plates are responsible for the earthquakes, tsunamis, the creation of volcanoes and mountains. There is a scientific explanation beyond all the things that we see and touch in this world.

As one tectonic plate that is under of another tectonic plate moves, that plate moves down into the mantle only by centimeters in a year. That small movement creates a huge impact on the land where we live in. that impact is what we call earthquakes. It destroys many structures in the land and kills many people. Earthquakes under the sea create tsunami, resulting huge tidal waves in to the lands. It creates huge current that fill flow towards the land. Movement of tectonic plates also creates mountains.




The land on the plate on top of another plate creates mountains. Volcanoes are also created. But where does the magma from the volcanoes came from? As the tectonic plate moves and one goes down of the other, it creates pressure underneath, at the upper mantle. The upper mantle consists of hot liquid hat has convection current circulating. As pressure rises, the magma will go up and finds a soft spot in the land and creates a volcano.

The world we live in is very complicated as we cannot see. We don’t know that one day, a big impact on our crust will suddenly happen. We should be ready to face that challenge and live our life as it seems to be our last.
