Continental Drift‚ why True? Continental drift is the process of large mass of land and rocks unceasingly moving for a long period of time‚ which can be explained by what is called "Plate Tectonics". Due to the fact that continental drift is a theory‚ there is evidence and other sets of statements to back it up. According to Wegener‚ a geologist stated that segments of the Earth has made continental drift true (possible) whilst other pieces of information supported that continental drift has happened

Inter-Tropical Convergence Zone‚ which is the area encircling the earth near the equator where the northeast and southeast trade winds come together. Solar heating in this region forces air to rise through convection that results in plenty of precipitation. In addition‚ as the air rises due to convection in such regions‚ the pressure of that area drops. Therefore a conclusion that can be made is that where the ICTZ lies‚ the pressure of the surrounding area is very low. The location of the ITCZ can vary

He was the first earth scientist to grasp the mechanical and thermal implications of mantle convection. He also widely applied the newly developed method of radioactive dating to minerals in the first attempt to quantitatively estimate the age of Earth. Holmes was able to determine the age of minerals and the rocks they are in in 1913. Holmes also

Contraction Theory • States that the Earth is gradually sinking. As the shrinkage occurs‚ the stronger and heavier blocks of the crust sink while the weaker strata are crowded and squeezed upward. c. Convection Theory • Is a theory which would account for publishing and folding of rocks through convection currents. This process is true when it occurs under a continental mass. d. Continental Drift Theory • Is a theory which accounts for diastrophic movement and for the folding and faulting along

the smoke particles visible under the microscope. This is called dark ground illumination. A small piece of black card prevents stray light from the lamp reaching the eye. The lamp is placed below the level of the glass rod in order to minimise convection. Procedure: [pic] 1. Fill the cell with smoke using a dropping pipette and cover it with a glass cover-slip. This will reduce the rate of loss of smoke from the cell 2. Place the cell on the microscope stage

“What evidence is there to support Alfred Wegener’s theory of continental drift?" Alfred Wegener‚ born November 1st 1880‚ was a German scientist who took a great interest in meteorology and paleoclimatology and in 1905 graduated from the University of Berlin with a Ph.D. in Astronomy. His most notable work was the theory of continental drift. However his theory was highly controversial at the time as he had little evidence‚ but as technology enhanced neumerous discoveries were made which helped

Introduction: The regulation of body temperature is called thermo-regulation. It is the ability of any organism to maintain the temperature of its body at normal level even when the temperature of the external environment is fluctuating. The normal temperature of the body of humans is approximately 37◦C or between the 98◦F-100◦F and it is called its core body temperature. This core temperature usually remains the same within a very short range of variations. This core temperature only

Using tactics that are considered ‘low’‚ they find a way to arrest those responsible in a federal court because the state courts were unjust. The events and convections used help to teach the viewer‚ get them thinking about the topics raised but at the same time amuse them and keep them entertained with the suspense and slight horror of the film.

what we call weather occurs in the troposphere. The uneven heating of the regions of the troposphere by the Sun causes convection currents and winds. Warm air from Earth’s surface rises and cold air above it rushes in to replace it. When warm air reaches the tropopause‚ it cannot go higher as the air above it (in the stratosphere) is warmer and lighter ... preventing much air convection beyond the tropopause. The tropopause acts like an invisible barrier and is the reason why most clouds form and weather
