Answer 1

Answer:

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

b. 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.

c. The ilam is situated in the Eastern part of the Nepal and the Kanchanpur is situated in the western part of the Nepal. And we all know that the eastern longitudes have earlier sunrises than the western longitudes. For this same reason the sunrise of ilam is earlier than the kanchanpur.

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.
