How do we have seasons?

I have written a short explanation to explain how earth has seasons.

Seasons are 4 divisions of a year like weather patterns which affects the temperature. These seasons are Winter, Autumn, Summer and Spring.

Winter is when coldness sweep in beneath our feet, Autumn is when all the summer leaves fall, Summer is when it is very hot and finally Spring is when the flowers and plants bloom.

Many people would say that earth’s axis is straight. That's where most people are wrong, earth’s axis is on a tilt. That exact tilt creates our seasons, “you never knew that, now you do.” So as earth tilts the hemisphere(north & south) closest to the sun gets Summer and the hemisphere facing away from the sun gets Winter. Spring and Autumn come when earth moves slightly 90 degrees anticlockwise (to be precise).

Earth, Uranus and Venus are the only planets tilted on its axis which mean they are also the only planets with seasons. Some last years others only last days.
