Great views of Leibniz

According to him, the land was originally in a molten state, and only by slow cooling into a hard ball, while there were first, for the most part glassy rocks, with, of course, and quartz was used as a glass. When the earth is cool enough, the water had fallen on its surface and pouring rain and formed a sea. These seas covered all the land first, and they have the first sedimentary rocks. On the spot voids or bubbles formed during the cooling of the earth, there have been landslides and the water gradually filled the basin. In this way, there were continuous changes over long periods of time until such time until an equilibrium is now observed.
