(f) Why does the Southern Hemisphere experience Winter and Summer Solstice in different times than that of the Northern Hemisphere?
(g) Why do the poles experience about six months day and six months night?
(a) The angle of inclination of the Earth’s axis with its orbital plane is 66 ½â—¦.
(b) Rotation:
Revolution:
(c) A year with 366 days is called leap year. It occurs once in four years on the month of February and it is 29th day of that month. It is also called intercalary year. The Earth do not take exact 365 days in an year and 24 hours in a day, so we add them as one extra day once in four year.
(d) Differences between summer and winter solstice are as follows:
|
Summer Solstice |
Winter Solstice |
|
Summer solstice occurs on 21st June in Northern Hemisphere. |
Winter Solstice occurs on 22nd December in Southern Hemisphere. |
|
The Northern Hemisphere experiences more heat and light. |
Southern Hemisphere experiences less heat and light. |
|
It is summer in Northern Hemisphere. |
It is winter in Southern Hemisphere. |
|
Days are longer and nights are shorter. |
Nights are longer and days are shorter. |
(e) On 23rd September and 21st March, the rays of sun directly falls on the equator. So, at that position neither of the poles are tilted. So at that specific or we can say a particular day the earth experiences equal days and nights and this is called as equinox.
(f) The Southern Hemisphere experience winter and summers solstice in different times than that of the Northern Hemisphere because:
(g) The poles experiences about six months day and six months night because:
