Earth has two sets of poles: the geographic poles and the magnetic poles. The geographic poles are located at the northemmost and southernmost ends of the earth. The location of the magnetic poles, on the other hand, are ( ア ) moving, This fact has several implications for navigation and transportation. Shifts in the position of the North Magnetic Pole are nothing new. Since 1831, scientists have been tracking its location. The movements are caused by changes in the flow of swirling molten iron in the earth's core which affect how the earth's magnetic field behaves. What is surprising to scientists is the speed at which the pole has been moving in recent years. For most of the 20th century, magnetic north was located around the northern parts of Canada. It drifted around, moving slowly north at an ( イ ) speed of approximately 10 kilometers per year. In recent decades, that rate has increased significantly to about 55 kilometers per year. The North Magnetic Pole is now moving away from Canada toward eastem Russia. While scientists can't fully explain how changes in the carth's molten core are affecting the pole's movement, they can map the earth's magnetic field. Doing so allows them to ( ウ) hé rate of change over time. This, in turn, provides information on how the magnetic field may shift in the future. Information on changes to the earth's magnetic field is used to produce the World Magnetic Model (WMM). This model is used as the basis for all fornms of modern navigation, from how ships move at sea to mapping software in smartphones. ( エ) in the model, caused by shifts in the real location of the North Magnetic Pole, can seriously impact almost all foms of modern transportation. The model is updated every five years, but in 2018, during routine checks of the 2015- 2020 model cycle, scientists noticed a problem. Because of the rapidly shifting pole, the WMM was close to being outside the acceptable limits for navigational errors. This forced the release of an updated version of the model、 It was revised ( オ ) in 2020, and the current version is expected to last until 2024, As well as keeping track of the WMM's accuracy, scientists continue investigating why the magnetic field is changing so dramatically. This essential work will ensure a safe journey for everyone navigating their way through the world.

greaty respected Greek philosopher Aristotle (384-322 BC), who claimed that heavy Objects naturally fall faster than light obiects. This hypothesis was considered to be true nearly 2000 years-mainly because nearly everyone who knew of Aristotle's Conclusions had such great respect for him as a thinker* that they simply assumed he Couldn t be wrong. Also, in Aristotle's time. air resistance was not recognized as an Iuence on how quickly an obiect falls We've all seen that stones fall faster than leaves Inuttering in the air. Without investigating further, we can easily accept false ideas. Ganleo very carefully examined 。 Aristotle's hypothesis. Then he did something that -Q 10 caught on and changed science forever. He experimented. Galileo showed the falseness of Aristotle's claim with a single experiment ー dropping heavy and light objects from the Leaning Tower of Pisa. Legend tells us that the objects fell at equal speeds. (3) In the SCientific spirit, one experiment that can be reproduced outweighs any authority, regardless of reputation or the number of advocates* CD 58
