trenches, plate tectonics explains all the features & movements of earther’s surfaces in both the past & present. Plate tectonics, the theory that earth’s external shell is separated into numerous plates which glide over the rocky internal layer of the core called the mantle. The plates act like a rigid & hard shell compared to earth’s mantle. The lithosphere is what the strong outer layer is referred to as. Developed between the 1950s all the way through to the 1970s, plate tectonics is the up-to-date

The Plate Tectonic theory The Plate Tectonic theory states that the continents have moved over hundreds of millions of years due to gigantic slabs of Earth underneath them known as tectonic plates. According to this theory, these plates are the reason why there are mountains, volcanoes, trenches, mid-ocean ridges, and other landforms. There are 4 plate boundaries that create mountains, volcanoes, trenches, and mid-ocean ridges.They are called; Subduction zone, convergent boundary, divergent boundary

Theory of Plate Tectonics The most important and vital development of plate tectonic theory and evolution appeared to be among the most crucial scientific achievements in the 20th century. The theory concept offers a relevant structure towards the knowledge of all natural Earth attributes. It additionally provides one particular framework with regard to the knowledge of both planet's origin and outlook. Notably, the evolution of life on the planet remains significantly impacted by plate tectonic

which relates to the theory of plate tectonics, as well as boundaries, hotspots, and forces. We begin with the PLate Tectonic Theory which developed along with many other theories to describe the world’s processes and common natural occurrences. In the theory, it describes how the Earth’s lithosphere is divided up into many different plates that push and pull which affects the creating of many of the Earth’s features like mountains, ocean ridges, earthquakes, etc. The plates have different boundaries

January 2011 Plate Tectonics and Associated Hazards (25 marks) a) The Philippines are located on the Philippine plate which is largely involved in the tectonic activity of the Pacific Ring of fire where you can find volcanoes and earthquakes which are two primary tectonic hazards, this is due to its location and the fact that numerous trenches are a strong piece of evidence to the presence of the sub-duction of tectonic plates. This makes me think that there is a strong degree to which this

The Development Theory of Plate Tectonics * Introduction In this report I will be describing the theory of the Plate tectonics and showing its main points of development. There are matches between the shapes of South America and Africa. The two continents look like pieces of a jigsaw. Alfred Wegner thought that this meant that the continents where moving. They had once been joined together. He looked for evidence which was recorded in their rocks. In 1912 Wegner presented the idea of continental

My article was about a sea floor spreading hypothesis that collates with the theory of plate tectonics. The belief of sea floor spreading was a theory that oceanic crust developed along submarine mountain zones, which is recognized as the mid-ocean ridge system, and spreads out horizontally away from them. This statement was the primary reasoning behind the development theory of plate tectonics. In 1960, an American geophysicist, Harry Hess suggested new found discoveries about the deep ocean floor

Plate Tectonics & the Pacific Northwest April Pilcher 7/18/16 GLG/150 Anna Foutz Plate Tectonics & the Pacific Northwest Plate tectonics is a scientific theory that tries to explain the movements of the Earth’s lithosphere that formed all of the landscape features we see today. The theory of plate tectonics says that the Earth’s lithosphere is made up of individual plates that are broken down into over a dozen different sized pieces of solid rock. The theory of plate tectonics was
