Plate Techtonics

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.

II: Plate tectonics shows the features and movement of the Earth. The theory of plate tectonics says that the outer shell of the earth is broken down into pieces often called plates (Korenaga). These plates hover over the mantle creating movement (Marshak). With plate tectonics you can determine the earth’s features without actually seeing it.

Plate tectonics are very dangerous when they collide,slide,and move apart. They can create mountains like the Appalachian Mountains that used to tower over everything then erosion took place. The Appalachian Mountains were formed by convergent boundaries, convergent boundaries are collide

Overall the plate tectonics theory does seem valid as there is lots of evidence to prove it right. For example fossils on either side of the ocean, climates being the same in different continents and hot spots. But there are some stronger pieces of evidence like the ring of

200 million years ago a supercontinent called Gondwana existed. It was made up of South America, Africa, Australia, India, and Antarctica. Fossil evidence shows that certain species have lived in multiple places, but these places are far apart. This proves that they lived in one place, but were separated from their ancestors when the plates split, causing earthquakes. In addition,

of the effects of plate tectonics acting over geologic time. The story begins with the

Explain the Theory of Plate Tectonics. The theory of plate tectonics is that plate tectonics is what moved pangea, a supercontinent with all the continents combined away from each other.

The theory of plate tectonics states that the Earth’s lithosphere (top layer of the Earth’s crust) is split up into rigid sections called plates that are moving relative to one another as they move on top of the underlying semi-molten mantle. These plates are either continental, The North American Plate, or oceanic, The Nazca Plate.

As of this month, the Trump Administration has announced removal of the DACA program and the Dreamers, who are immigrants currently participating in this program. However, after this notice was made, there are different sides on whether this decision will improve or damage America’s future. Determining whether DACA is beneficial or harmful to our country is important because this can create more awareness of the impacts that affect huge components of America, especially our country’s economy. If America kept the DACA program, this can be beneficial in many ways towards the future of our economy.

Plate tectonics is the scientific theory that attempts to explain the movements of the Earth's lithosphere that have formed the landscape features we see across the globe today” (Briney). Geology defines “plate” as a large slab of solid rock, and “tectonics” is part of the Greek root word for “to build.” Together the words define how the Earth’s surface is built up of moving plates. The theory of plate tectonics dictates that individual plates, broken down into large and small sections of rock, form Earth’s lithosphere. These fragmented bodies of rock move along each other atop the Earth’s liquid lower mantle to create the plate boundaries that have shaped Earth’s landscape. Plate tectonics originated from meteorologist Alfred Wegener’s theory, developed in the early 20th century. In 1912, he realized that the east coast of South America and the west coast of Africa appeared to piece together like a jigsaw puzzle. He further examined the globe and deduced that all of Earth’s continents could somehow be assembled together and proposed the idea that the continents had once been linked in a single supercontinent called Pangaea. To explain today’s position of the continents, Wegener theorized that they began to drift apart approximately 300 million years ago. This theory

Two plates can separate to split continents apart, to form new oceans, or to enlarge existing oceans by forming new crust in giant rifts in the ocean floor. Plates can converge and collide, forming chains of volcanic islands and deep trenches in the ocean, volcanic mountain belts along coasts, or giant belts of folded mountains between continental masses. These movements and their physical consequences are studied in the branch of geology called plate

Earthquakes, volcanoes, mountains and the Earth’s crust are unique yet have one common denominator; the amazing topic of plate tectonics. Plate tectonics has a place or specifically places a role in each of these natural wonders of the world. In the following, Team C will discuss the theory of plate tectonics and how the theory shaped the form and composition of the movement within the Midwest region of the United States. A discussion of various geological events and the types of rocks that formed because of these events will also be covered including the importance of the economic value of these rocks to the Midwest region

Plate Tectonics is a scientific theory which study how the Earth’s plates are driven and shaped by geological forces to keep them in constant movement. The theory explains the present-day tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity, and volcanism in a series of linear belt.

The viscosity of this base is a function of the temperature. The study of shifting continental plates is called Plate Tectonics. Plate Tectonics allows scientists to locate regions of geothermal heat emission. Shifting continental plates cause weak spots or gaps between plates where geothermal heat is more likely to seep through the crust. These gaps are called Subduction Zones.

     Earthquakes, called temblors by scientists, occur almost continuously. Fortunately, most of them can be detected only by sensitive instruments called seismographs. Others are felt as small tremors. Some of the rest, however, cause major catastrophes. They
