How does winter occur in India?
Winter, occurring from December to February. The year’s coldest months are December and January, when temperatures average around 10–15 °C (50–59 °F) in the northwest; temperatures rise as one proceeds towards the equator, peaking around 20–25 °C (68–77 °F) in mainland India’s southeast.
Why does it get cold in the winter?
In the winter, when the northern hemisphere is pointed away from the sun slightly, the sun’s rays come in at an angle and have less of an impact. This makes winter cold!
Where do the four seasons occur?
The four seasons happen because of the tilt of the Earth’s axis. At different times of the year, the sun’s rays hit different parts of the globe more directly. The angle of the Earth’s axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth’s axis, we wouldn’t have seasons.
What are the two factors that cause seasons?
Remind students that the two reasons seasons occur are the tilt of a planet’s axis and its orbit around the sun.
Which are winter months?
In the Northern Hemisphere it is commonly regarded as extending from the winter solstice (year’s shortest day), December 21 or 22, to the vernal equinox (day and night equal in length), March 20 or 21, and in the Southern Hemisphere from June 21 or 22 to September 22 or 23.
How does Spring occur?
According to the astronomical definition, spring occurs when the Sun’s rays strike the equator at noon from directly overhead. This particular time varies from year to year due to variations in the Earth’s orbit about the Sun.
