The availability of experiencing the four seasons of spring, summer, autumn, and winter depends on your location.
Those who live in the countries near the equator experience constant temperatures throughout the year where winters and summers are indiscernible due to their position on the outer curve of the earth where it receives constant light from the sun. While areas in the north and south are able to experience the changing of seasons more significantly.
The reason we experience seasons is because of the tilting of the earth towards the sun. How the planet rotates around its axis affects the way we experience the seasons. Such as the summer and winter solstice being our longest and shortest days of the year.
Moreover, other factors also affect the way we experience seasons significantly, therefore the seasons have a wide variety of what we may experience during the year and current location.
