What is plate tectonics

There are different continental plates on our earth. The parts that we see today as large land masses on the map were not always where they are now. At the beginning of the 20th century, the German researcher Alfred Wegener was able to support the theory that the continents move with his research and investigations. We now know that about 225 million years ago there was a great continent called Pangea, from which our present-day continents emerged

We call the outer solid shell of the earth the lithosphere. It has broken into rigid plates and these are slowly moving on the tough asthenosphere (part of the earth's mantle). The puzzle of the panels is made up of 6 large panels and a large number of small panels. The boundaries of the plates are not always identical to the boundaries of the continents known to us - they can be completely or partially under water. Since it is warmer in the interior of our earth, there are equalizing currents in the tough material of the asthenosphere - similar to what happens in the soup pot when we cook. As a result, the lithospheric plates are moved slowly, a few centimeters a year. Over the course of millions of years, the face of the earth can change completely, with the plates colliding (converging), moving away from each other (diverging), or past each other. Mountains and volcanoes can then arise at the plate boundaries. Earthquakes also occur at plate boundaries. Through them we are reminded again and again that our seemingly solid ground is still in motion.
