What Causes Seasons to Change? for Kids
What are seasons?
Do you wear the same type of dress every day to your school for a whole year?
In most of the places, students have two or three type dresses for the school- one for hot days and one for cold days. And for many days, you have to carry an umbrella with you if you happen to live in a place where there’re rains during few months of the year.
And at few places, it snows for few months and kids have to wear extra layers of clothes to save themselves from extra cold.
These different types of periods that have different type of weather for few months are called seasons. The months which are hot is the summer season whereas the period of cold months is called winter season.
A year is divided into four types of seasons: i) Summer ii) Spring iii) Winter iv) Fall
These seasons follow a fixed pattern every year. They follow each other.
More or less seasons:
Few places there are additional seasons also. For example, if some place has few months of rains, that is called rainy season and similarly if you live in a place where it snows for few months, you might have a snow-season.
And few places have only one season during the full year – for example most of the places in Africa have only season i.e. summer throughout the year.
More or less seasons at certain places happen due to unique position of these places on the planet earth.
What causes seasons to change?
Have you ever wondered why we can’t have same type of weather throughout the full year? Why we don’t have summers or winters for the full year?
To understand the reasons for change in seasons, you need to remember few facts:
a) Earth spins on an axis as it moves around the sun.
b) This axis is an imaginary line which runs through the south and north pole.
c) Earth’s axis is not straight, it is tilted at a certain angle.
d) Earth takes 365 days to complete one orbit of the sun.
The tilt in the earth’s axis and its movement around the sun causes seasons. During a year (365 days) , some parts of the earth are more closer to the sun for few months and they get direct sunlight. Direct sunlight causes hot days and, in those parts, we get summer. Whereas during the same period, some parts of the earth are away from the sun, and due to the tilt of earth’s axis, these places don’t get direct sunlight. Hence these places have winter.
But due to earth’s movement, these places keep exchanging their positions during the year. So the place which has summer for few months would have winter in other months and vice versa.
In between summer and winter, these places also have spring and fall seasons.
In this animated video, two kids discuss about various seasons in an interesting and simple way. Teachers can use this video for home schooling as well as to teach the students in the class room.
