Earth has seasons because

• it rotates on its axis exposing 1/2 to sunlight and 1/2 to darkness
• its axis is tilted as it revolves around the sun leading to a differential of direct sunlight
• the distance between Earth and the sun changes; when we are closer, we are hotter
• the temperature of the sun changes.
