The Earth’s Plate Tectonics
James Hutton was the first scientist to address the Earth was millions of years old, as well as alive and is continuously being formed. Charles Lyell popularized uniformitarianism, and believed the Earth was being shaped by slow moving forces. Alfred Wegener introduced the foundation for the theory of continental drift. Wegener was one of the first to recognize and have an understanding of how the Earth works which required data and information from earth sciences. In the 1960s, the theory for the continental drift became known as the theory of plate tectonics or plate building. Wegener’s observations and ideas clearly served for the development of the plate tectonics three decades later.

Scientific Discoveries of Plate Tectonics Have Changed Over Time
• • • • • Evidence from 225 millions years ago believe that all land masses of the Earth were interconnected together as a supercontinent known as Pangaea. Hutton determined the center of the Earth was a massive heat source, that continues to destroy and reform rocks. Lyell recognized the Earth was old due to the conditions of erosion and by his study of fossils that were embedded in stones was a time indicator. One of the main natural phenomena that has changed our understanding of nature is the plate tectonic theory. The theory was developed recently in 1960 and as discussed by several scientists, the theory states that the Earth was once a compact land mass. This is as opposed to the natural theory of creation that states that the Earth was formed as it is today with the different continents. The tectonic theory was further reinforced by the study of the continental drift.
