A-When Magellan’s crew left Spain to sail around the world, it took nearly three years to return to spain. Although Magellan had died, and only a skeleton crew arrived back in Spain, they had the incorrect day on their calendars, they were a day behind, although accused of failing to record daily in the log , what was the correct explanation as to why they were a day behind?
B-
The above problem demonstrates the need for an international dateline, look at a world map and suggest a good place for a dateline where a minimum of land is affected. ( for example an international dateline would not be appropriate in the middle of North America or Europe?
6-Now , describe the location of the actual dateline.
A- They crossed the International Date line. Even though the line did not exist, the fact that the earth is round and rotates once a day makes it necessary to add aday when going west, because you see the sun set one less time than people who stay in the same part of the Earth
B- The place where the International Date line is drawn in an area of widely separated islands. Check it out for yourself on a map.
i did check it but i could not get it ..
A- When Magellan's crew sailed around the world, they crossed the International Date Line without realizing it. At that time, the International Date Line did not exist, but the concept behind it still applied. The Earth is round and rotates once every 24 hours, which means that when you travel west, you see the sun set one less time than people who stay in the same part of the Earth. This results in a discrepancy in the calendar days. So, even though they didn't record daily in the log, the crew ended up being a day behind because they didn't account for the loss of a day while traveling westward.
B- The International Date Line is located in an area of widely separated islands in the Pacific Ocean. It is purposely placed in an area with minimal land impact to minimize the disruptions caused by changing dates. If you look at a world map, you can identify the general location of the International Date Line by finding the Pacific Ocean and looking for the cluster of islands around that area. This location allows for a relatively smooth transition in date changes as you cross the line while traveling from west to east or vice versa.
