taking seriously 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

Tectonics Division of Pakistan Defination: Tectonics zones of Pakistan are the Eurasian Plate‚ Arabian Plate and Indian Plate which is part of Indo-Australian Plate. Eurasian Plate: The Eurasian Plate is a tectonic plate which includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia)‚ with the notable exceptions of the Indian subcontinent‚ the Arabian subcontinent‚ and the area east of the Chersky Range in East Siberia. It also

Title: Erythrocyte Sedimentation Rate (ESR) Aim: To measure the erythrocyte sedimentation rate of a patient to see if there could be anything wrong. Introduction: The erythrocyte sedimentation rate (ESR) is the distance that the red blood cells sediment in a specific time interval. ESR is an easy‚ inexpensive and non-specific test that is used to help protect conditions associated with acute and chronic inflammation including infections‚ cancers and autoimmune diseases. ESR is said to be non-specific

Plate tectonic theory is a widely excepted theory that the Earth’s lithosphere is made up of plates‚ both oceanic and continental‚ which slowly move due to convection currents in the mantle and the asthenosphere. However‚ it is very hard to be certain as we can’t see the structure of the Earth‚ so some people do not agree with it. This theory saw the introduction of what we know today to be tectonic plates. Tectonic plates occur where there is radioactive decay in the core and temperatures are extremely

Drivers who are on their p-plates are often involved in horrifying crash statistics and are perceived as reckless‚ irresponsible and foolish drivers. Statistics show that 26 per cent of all road fatalities are p-plate drivers‚ and that a driver with a p1 license is four times more likely to be involved in a fatal crash than a driver over

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

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

Microbiology Instructor: Dirk VandePol Date: 6/21/2013 Streak Plate Isolation for Obtaining Pure Culture 1. When an agar plate is inoculated‚ why is the loop sterilized after the initial inoculation in put on? Ans: We use agar plate to inoculate microbes by zipping the loop on the agar several times. We streak on the agar plate four time‚ propose is to isolate the unknown bacteria. Therefore‚ the first time to streak on the plate‚ there are million of bacteria on the loop. For that reason‚

Constructive boundaries occur when two plates move apart which causes new oceanic crust to be formed and mid-ocean ridges are created by the build-up of molten rock on the seafloor due to the mantle building up. This new crust pushes the old crust aside and forcing the plates apart at a very slow rate. Basaltic lava rises which means new crust is being added continuously. Rift valleys are formed at constructive boundaries‚ where convection current causes the crust to be pulled apart causing fractures
