Answer:
Explanation:
(b)In other countries like USA , Canada & Russia have more than one standard time because their longitudinal extent is large. India longitudinal extent is also 30°. Therefore it is advisable to use more than one Standard Time.
(c)In the case of India, the time difference between the westernmost part of India and the easternmost point is approximately two hours, the effect of which is that the sun rises and sets much earlier than it does in the rest of the country.
(d)Antarctica has six months of daylight in its summer and six months of darkness in its winter. The seasons are caused by the tilt of Earth's axis in relation to the sun. The direction of the tilt never changes. But as the Earth orbits the sun, different parts of the planet are exposed to direct sunlight.
(e)Time zones are based on the fact that it takes one hour for the earth to rotate 15 degrees on its axis. ... That means that large countries that span more than 30 degrees of longitude usually have different time zones.
Answer:
(b) Because Canada is the second biggest country on the earth and needs a lot of time zones to cover the country.The biggest country on the earth is Russia which has 11 time zones
Canada extends from the Pacific Ocean to Atlantic ocean . Time zones generally change when the time difference is greater than one hour . So, Canada's time zones are Pacific standard time,Central standard time,Eastern standard time,Atlantic standard time,and Newfoundland standard time.
(c) It is exactly two hours, the effect of which is that sun rises and sets much earlier than it does in the rest of the country
