are from a ridge because when new rocks form at the ridge‚ old rocks move away from the centre and this rocks stack along the end of sediments which pile up for long time that creates thick sediments‚! ! 10. How does sea floor spreading explain the movement of tectonic plates?! - Sea floor spreading in movement of tectonic plates is called divergent‚ the separation of two plate. This can be proved because magma comes out from the fault of ridge which means plate has open and it’s realising the magma

RAPPEL A L’ORDRE: THE CASE FOR THE TECTONIC Kenneth Frampton Kenneth Frampton’s ‘Rappel a L’Ordre: The Case for the Tectonic’ identifies the issues in relation to the tectonic form‚ his intention is to make architecture step apart of just being part of a scenographic interpretation. The word tectonic is addressed from its different origins but overall referring to carpentry and its evolution into an aspect of poetry and art of construction. Tectonic objects are seen in two different forms;

The theory of plate tectonics states that the Earth’s lithosphere is broken up into many different pieces separated by jagged cracks. These are called the tectonic plates. They are in slow‚ constant motion pushed by the convection currents in Earth’s asthenosphere. This theory explains the process of sea floor spreading at mid-ocean ridges‚ and subduction at deep ocean trenches. It was proposed by J. Tuzo Wilson in 1965. He combined the discoveries of Harry Hess and Alfred Wegner to support this

until the 1960. This study is called plate tectonics‚ and it helps explain the continental drift‚ the spreading of the seafloor‚ why volcanoes erupt and how mountains are formed. The mountain range that runs from the northern tip of Alaska to the southern tip of South America were formed by the buckling of crustal rocks that crash into the edge of North and South America. The land folds under the pressure of the colliding plates and pushes up sedimentary rock up to create mountains. It takes three

WHAT ARE ROCKS? What are Rocks? Making up most of the Earth’s crust‚ rocks are usually defined as a mixture of common minerals. Rocks can be hard or soft‚ as small as a grain or as large as a building. Combined with the effects of weathering and vegetation (vegetation can also weather rock as the tree or bush is "yanked" out of the ground by forces of wind or by merely falling over after it has died. Root systems tend to go under the surface and attach themselves to

The History of plate tectonics Before the plate tectonics revolution of the 1960’s geographers had a very basic understanding of global geological phenomena’s. while there had been many theory’s put fort that were used to try and explain these phenomena’s none had been completely successful till finally In the 1960’s The theory of plate tectonics was put forth. It was truly a unifying concept as it helps us to explain and finally understand many different aspects of geography such as the geography

Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates. He put forward the idea that all the earth’s continents were once conjoined in one supercontinent called Pangaea‚ and that these continents were moved by convection currents over a period

Plate Tectonics: An Essay By: Grace Park Science 9 Mr. Achor 11-22-11 In the early 1900’s‚ scientists began to ask questions about the earth and it’s continents. Why are the same fossils found on opposite sides of the globe? Why do South America and Africa seem to fit together like two pieces of a jigsaw puzzle? Some scientists went to rather extreme measures to explain these strange phenomenons. Others took the time to come up with detailed theories
