John Wilson discovered the Theory of Plate Tectonics. He contributed himself to the development of the Plate Tectonics Theory in 1963. The theory that made this important to this development‚ was The Theory of Continental Drift. To develop or prove his Theory he gathered info from other scientists like Alfred Wegener‚ Harry Hess‚ Eduard Suess‚ and more. Alfred Wegener proved that the plates could move‚ but he couldn’t develop the source that moved them. Harry Hess discovered the process of Seafloor

Oklahoma during 2011 from franking and injecting wells. Geologists say it’s not the extraction of oil or gas that is causing the earthquakes. It’s when waste fracking fluid is injected back into earth that they believe lubricates faults‚ causing tectonic plates to slip more easily. As the number of franking increase in Oklahoma so do the numbers of earthquakes. It has become so severe that it sky rocketed from being a dozen in 2008 to over a thousand in 2010. As franking causes earthquakes from putting

hazard groups: tectonic hazards (geophysical) and hydro-meteorological hazards. This means they are likely to be where plate boundaries intersect with major storm belts and they are also in areas of high human concentration in low or medium developed countries because this effects whether or not the country will be prepared thoroughly enough and whether it can recover quickly. The Philippines lies on a boundary between the Philippine and Eurasian tectonic plates‚ whereby the Eurasian plate is sub ducted

The Earth consists of four concentric layers: inner core‚ outer core‚ mantle . mantle: ]. The crust is made up of tectonic plates [tectonic plates: Large areas of the Earth’s crust that move slowly on the upper part of the mantle‚ often colliding and moving away from each other. ]‚ which are in constant motion. Earthquakes and volcanoes are most likely to occur at plate boundaries. 1.1 The structure of the Earth The Earth is made up of four distinct layers: 1. The inner core is in the centre

The causes of tectonic plate movement and how different processes have shaped New Zealand’s landforms occur nearly every single day. In fact one of these processes is happening right now‚ somewhere on the Earth. The 3 major processes are folding‚ faulting and volcanism. While these take place‚ another “force” is also acting‚ changing the shape of our continents‚ and Earth itself‚ the tectonic plate movement. Earth’s outer shell‚ long thought to be a continuous‚ unbroken‚ crust is actually a fluid

An Introduction to Structural Geology Introduction Structural geology is the study of the features formed by geological processes. Features include faults‚ folds and dipping strata. Geologists can work out the order of events and see which events are related by taking fairly simple measurements and using simple methods. Measurements and Techniques The most obvious thing to do when trying to decipher the structural history of a formation is to describe it. One way of doing this is to measure the dip and strike

Tectonics and Continental Drift Past and Present Locations Abstract When we look at our earth’s surface now it has seven continents‚ and five of them are divided by the oceans that surround them. In 1912 Alfred Wegner (1880-1930)‚ came up with a theory called the continental drift; stating that over three hundred years ago all seven continents were once one super continent called Pangaea. Wegner tried to convince other scientists and geologist for many years that the continents

Plate tectonics help us to explain the process of folding. According to the theory of plate tectonics‚ the earth’s crust is broken up into sections called plates. These plates float on the semi-molten mantle. Thermal convection currents in the mantle drag these plates in different directions resulting in tectonic activity. Folding occurs when rock layers that were originally horizontal are bent into a series of wave-like folds. As a result of this collision of the earth’s tectonic plates‚ the

MAJOR FAULT LINES The Philippine Sea Plate or Philippine Plate is a tectonic plate comprising oceanic lithosphere that lies beneath the Philippine Sea‚ to the east of the Philippines. Most segments of the Philippines‚ including northern Luzon‚ are part of the Philippine Mobile Belt‚ which is geologically and tectonically separate from the Philippine Sea Plate. The North American Plate is a tectonic plate covering most of North America‚ Greenland‚ Cuba‚ Bahamas‚ and parts ofIceland and the Azores

Have you ever wondered where mountains come from‚ why there is a sea floor‚ island arcs or even volcano and what plate tectonic have to do with this? Well worry no more as all your question on the earth’s surfaced topographic relief elements and plate tectonics are about to be answered. The first question that might come to mind is what is a relief? A relief is a land
