Why is time difference between each meridian of longitude 4 minutes?
Answer: The earth has 360 imaginary lines called longitude or meridians running vertically between the poles. So the time difference between each longitude in 4 mins.
What is the time difference for every 1 degree latitude?
The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on. In India, the standard meridian is 82-and-half degree.
What is the time difference for every 1 minute longitude difference?
The correct answer is 4 seconds. Longitude is usually measured in degrees, minutes, and seconds, and 4 seconds time differences occur for every 1-minute longitudinal difference. 15 minutes of longitude = 1 minute difference; 1 minute of longitude = 4 seconds difference.
What is the time difference between each latitude?
The Zero degrees longitude is an imaginary line known as the ‘Prime Meridian’. 5. There is a close relationship between time and longitude. The Earth rotates on its axis at a rate of 3600 degree per day or we can say 150 per hour….Difference between latitudes and longitudes.
| Latitude | Longitude |
|---|---|
| There are 181 lines of latitudes | There are 360 lines of latitudes |
Why is there a 4 minute difference?
Why is the solar day about 4 minutes longer than the sidereal day? Earth travels about 1 degrees per day around its orbit, a solar day requires about 1 degrees of extra rotation compared to a sidereal day. This extra 1 degree rotation takes about 1/360 of Earth’s rotation period, which is about 4 minutes.
Why is there a difference in four minutes between two adjacent longitudes?
The earth revolves around its axis and the sun completes a revolution once every twenty four hours. 360 degrees of longitudinal lines divided by twenty four hours is four minutes per longitude. The sun is positioned at 360 degrees at 24 hours, 15 degrees at 1 hour and 1 degree per four minutes.
What is the time difference if the difference in their longitudes is 30?
| Summary of finding longitude using time difference example | |
|---|---|
| time at your location | 12 pm (noon) |
| longitude difference | 2 hours x 15°/hr = 30° |
| are you E or W of 0°? | West because Greenwich time is later |
| your longitude (reference +/- difference) | 30° west of 0° = 30°W |
Why the difference between IST and GMT is 5 hours and 30 minutes?
Answer: The longitude difference between Mirzapur and the United Kingdom’s Royal Observatory at Greenwich translates to an exact time difference of 5 hours 30 minutes. So, The latitudinal distance between London and Mirzapur is the reason for difference in times.
Why the time is different in different countries?
As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. As your location on Earth rotates into sunlight, you see the sun rise. Since different parts of Earth enter and exit daylight at different times, we need different time zones.
