(1)__________________________, a German meteorologist, proposed a theory that about 200 million years ago, the continents were once a large and mass. He called this landmass (2)____________, a Greek word which means “All Earth.” The (3)______________________________ explains that the Earth’s continents were once joined together but gradually drifted apart. Alfred Wegener brought together several lines of evidence to support his theory of continental drift. These evidences are (4)_____________________,(5)____________________,(6)____________________ , and (7)__________________________. In the early 1960’s, scientist (8)______________________, together with (9)_______________________, suggested an explanation to the continental drift. This is the (10) __________________________________. According to this theory, hot, less dense material from below the earth’s crust rises towards the surface at the mid-ocean ridge. This material flows sideways carrying the seafloor away from the ridge and creates a crack in the crust. The magma flows out of the crack, cools down and becomes the new seafloor. (11)________________________ is also called magnetic ‘flip’ of the Earth. It happens when the North Pole is transformed into a South Pole and the South Pole becomes the North Pole. This is due to the change in the direction of flow in the (12) ________________.
