b. International Date Line is irregular in shape.
C. The sun rises in llam about half an hour earlier than in Kanchanpur.
d. The sun rises in the east and sets in the West.

please answer all the question

I will mark as brainlist to the correct answer

2:Local time indicates the time of a place determined on the basis of apparent movement of the sun. Standard time refers to the fixed time for places falling in the same meridian, set in a country by law. ... Remains same for a particular country. Places on the same longitude have same local time.

3: It takes 4 minutes to travel from one longitude to another. So, generally 1 degree difference in Longitude, causes a difference of 4 minutes. The places located in the East of the Prime Meridian are ahead in time to the places located in the Western Hemisphere.The time calculated on the basis of the distance between prime meridian and the longitude of a certain place in known as local time.

When we measure Nepal's standard time from the prime meridian, It is 5 hours and 45 minutes (86.25° 4 minutes= 345 minutes) ahead of the GMT.

4a: The countries like USA and Russia have adopted more than one standard time due to their great longitudinal extent.

Explanation: The local time of different locations have different meridian values.

4b: The IDL called a calendar line because it mostly runs through the sparsely populated central pacific ocean. It is irregular in shape because it is an imaginary line, like longitudes and latitudes, to avoid any confusion of date, this line is drawn through where the sea lies and not land.

4c: because of the longtidudes

4d: The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins -- toward the east. ... Earth rotates or spins toward the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.
