Answer:
a)Why do we have standard time?
Answer:The time of a place depends on the longitude that passes through it. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it. ... Thus, we need a standard meridian for the country. In India 82 ½ °E longitude determines the standard time.
b)Differentiate summer and winter
Answer. :
:The summer solstice occurs when the sun reaches its highest point in the Northern Hemisphere. The regions of the north of the equator receive direct sunlight on the earth making the days longer, and nights shorter. Winter solstice is when the sun reaches its lowest point in the Northern Hemisphere. In the case of the winter solstice, the days are shorter and the nights are longer because the north of the equator does not get direct sunlight on the earth. Apart from that, the summer solstice occurs every year between 20 and 22 June. On the other hand, the winter solstice falls between 21 and 22 December every year. During the summer solstice, all days are longer than 12 hours and in the winter solstice, all days are shorter than 12 hours.

This is the day when the North Pole is titled closet to the sun; making it the longest day for those living in the Northern Hemisphere. Winter solstice occurs when the North Pole furthest from the sun; making it is the shortest day of the year. At the winter solstice, the sun lies directly over the Tropic of Capricorn This position of the sun during the summer and winter solstice also determines the occurrence of other seasons like spring and autumn. For example, in between winter and summer solstice, there are two times when the tilt of the earth is zero (not too far, not too close). When the tilt is zero, that’s when we witness the first day of fall or the first day of spring
