Question
Why are physical geographers interested in globalization of the economy? Why is a distance covered by 1 degree of longitude at the equator different from the distance covered by 1 degree of longitude at a latitude of 45 degree N? What is the significance of aphelion and perihelion in Earth's seasons? In terms of the change of seasons, explain the significance of the Tropic of Cancer, the Tropic of Capricorn, the Arctic Circle, and the Antarctic Circle. Is the noon Sun ever directly overhead in Detroit, Michigan (42 degree N)? If not, on which day of the year is the noon Sun highest in the sky there? Lowest?Explanation / Answer
ANSWER:
1) Many patterns and processes in the natural environment can be influenced by economic activity-such as the consequences of the extraction of resources or the burning fossil fuels;economic activity in one part of the world can influence the environment in another part of the world.
2) Because the meridians converge at the poles, he distance of 1 degree of longitude is greatest at the equator and diminishes to zero at the poles, whereas the distance of 1 degree of latitude varies only slightly.
3) Two additional factors in the relationships of Earth and Sun-inclination and polarity- work together with rotation and revolution to produce the change of seasons. Aphelion and perihelion are important parts of this significant event.
4) The Tropic of Cancer is the circle marking the latitude 23.5 degrees north, where the sun is directly overhead at noon on June 21, the beginning of summer in the northern hemisphere. The Tropic of Capricorn is the circle marking the latitude 23.5 degrees south where the sun is directly overhead at noon on December 21, the beginning of win-ter in the northern hemisphere. The June solstice in the North Hemisphere is called summer solstice and the winter solstice in Southern Hemisphere. Basically summer at the Arctic circle means there is a winter at the antarctic and vice versa.
5) No, because the sun never reaches that high north, on June 21 it would be the highest, and on December 23 it would be the lowest.
