Plate Tectonics

Since the beginning of humanity, people had a miracle about how our planet was formed. Scientists who have been interested in this field for many years have generated many different theories for our planet. Before the 20th century, scientists and geologists believed that the structure of the mountains was due to the tightening of the earth caused by the gradual cooling of the lava. In 1900, American scientist Joseph Le Conte published an article on Appleton 's Popular Scientific Monthly.

About 30 years ago geologists developed the theory of plate tectonics - the theory that the Earth's crust was divided into large plates called tectonic plates fixed together like puzzle pieces. The structural plate is located between 200 km (seabed) and 15 km (seabed) thick. Geologists believe that the tectonic plate floats on the lava of the mantle and moves very slowly. Each continent has its own tectonic plate (see Figure 3), continuous slow motion of the plate leads to movement of the continent.

Tectonic Plate Tectonics is a relatively new theory that revolutionized the way geologists think about the Earth. According to this theory, the surface of the earth is divided into large plates. The size and location of these plates will change with time. The assumption of continental migration was developed mainly by German Alfred Wegner. The edges of these plates move with each other and are places of severe geological activity such as earthquakes, volcanoes and mountains. In this chapter we will explain various theoretical aspects of plate tectonics. This helps to understand how the Earth is built and how it functions internally. The center of this theory is that the surface of the earth consists of several large structural plates and several small structural plates.

Plate tectonics are defined as solid rocks that build the surface of the earth. The theory of plate tectonics is the theory used by geologists to help explain the process and events of the surface. The term board means that the big earth is always moving, that is, it means lithosphere plate. Construction means how the continent is formed and moves with time. This is the theory that most geologists will accept what will happen on our continent. It states that the Earth consists of two layers, and a material effect worksheet for Phoenix University structural plate movement from Visual Earth Sciences, by Merali, Z.

His theory of continental migration has been suspected by the scientific community. 1. Describe the three types of evidence Wegener uses
