What Caused the Earth to Develop Layers as It Cooled
What caused Earth to develop layers as it cooled. Differences in density caused earth to develop layers as it cooledThe earth has. What Are The Earth S Layers Earths crust is the planets thinnest layer accounting for just 1 of Earths mass. . Over the course of a few hundred million years the planet began to cool and oceans of liquid water formed. Recent evidence suggests the oceans may have begun forming as early as 44 Ga. As Earth cooled an atmosphere formed mainly from gases spewed from volcanoes. The surface was molten. After about half a billion years Earths surface cooled and solidified enough for water to collect on it. As the Earth cooled clouds formed. Two common types of fog are called radiation fog and advection fog. Due to this the outermost layer is made of the lightest materials such as rocks and granites and the innermost layer consists of nickel and iron. 45 billion years ago extreme tempera...
