Why Is The Theory Of Plate Tectonics True
The theory of plate tectonics states that the continents used to be together, and they have slowly moved apart. Some of us people believe it is fake, or some of us believe it is true. We believe that these continents used to be together and they were called Pangea. I agree with Alfred Wegner and I will explain why the claim is true because of these following reasons; the location of earthquakes, fossil evidence, and the age of the rocks. All of these earthquakes have occurred on the continental boundaries. Also, there are many earthquakes in the center of the oceans between the continents. These earthquakes happen along the edges of continents showing that the continents must have been moving and have once been together. If you look at
Mya Seaway Research Paper
1677 Words | 7 PagesINTRODUCTION The Cretaceous Period, spanning 65.5-146 million years ago (Mya), was a world different from what we are familiar with today. Planetary changes during this period included the extinction of dinosaurs and drastic global warming. The breakup of the super continent Pangea had started about 30 Mya, and seaways had begun to form and cover landmass that had once been a part of the super continent (Geologic Time). Today, scientists know that one of these landmasses, the North American continent as we now know it, was at one point covered by a vast inland sea known as the Western Interior Seaway.

Effect Of Tectonic Activity On Canadian Shield
373 Words | 2 PagesThe Canadian Shield is arguably the best land form region. Tectonic forces and glaciation have combined to shape the Canadian shield, making it different from other Canadian landform regions, directly affecting economic activity. Firstly, Tectonic Activity created the base of the Canadian Shield is 2.5 billion years old craton made of igneous rock. Tectonic activity directly affects the Canadian Shield to this day, because many economic activities take place on the rock.
