What Causes the ‘Change of Seasons’ and Why Does It Happen Every Year?

The Earth is tilted, and it goes around the Sun. Imagine you're on a spinning chair that circles a lamp. When your back faces the light, it's like winter, colder. When you face the light, it's summer, warmer. Every year, the Earth keeps doing this dance with the Sun, so seasons come again and again.
