Seasons are different climate patterns that happen throughout different times in a year! Places on Earth experience seasons at different times. Some seasons are noticeable and others are not. We have seasons because the Earth is slightly tilted on it’s axis. An axis is an imaginary rod going from the top to the bottom where a planet spins on. Earth is tilted 23.5°! Scientists think that a comet or asteroid hit Earth millions of years ago and tilted it on it’s axis! The tilt of the Earth exposes different parts of the Earth away or toward the Sun. When it is summer in the Northern Hemisphere, or top half of the Earth, it is winter in the Southern Hemisphere. This is because the Northern Hemisphere would be tilted towards the Sun and the Southern Hemisphere would be tilted away from the Sun. Being tilted towards the Sun causes warm and hot seasons, like summer and spring. Being tilted away from the Sun causes colder seasons, like fall and winter.
