What cause the seasons?

What causes the Seasons on Earth? You may be wandering what causes it. You see, the Earth is on a tilt and the axis that we revolve around causes it. Due to that tilt when we revolve around Sun is when it changes seasons. So when the Northern Hemisphere is facing the Sun its summer. But when its not facing the sun is when it is winter here in the Northern Hemisphere. As you can see the reasons that we have seasons are because of the Earths tilt.
