Answer:
d)Because Canada is the second biggest country on Earth and needs a lot of time zones to cover the country.
a)Noon is the time of the day when the Sun is at its highest position.Earth is round, noon happens at different times in different places. This leads to the concept of local time.
b)countries located in different longitudes have different local times.international coordination between countries, the local time at Greenwich (Greenwich Mean Time) in England is considered to be the international standard time.
c)The Earth has been divided into 24 time zones of one hour each. Each of these zones covers 15 degrees of longitude.the local time differs by 4 minutes at every longitude
The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat.
This causes a time lag of 2 hrs from Gujarat to Arunachal Pradesh to avoid confusion and to have a standard time for reference, The 82.30'Eastern Longitude has been taken as the standard time for the whole country.
The local time at this Meridian has been accepted as the Indian Standard Time (IST) throughout the country because it passes through the middle of the country.
