The Earth's axis is not perpendicular to its orbital plane around the sun. It is tilted at a constant angle of approximately 23.5 degrees. This tilt is the fundamental reason we have seasons. As the Earth revolves around the sun, different hemispheres are tilted towards or away from the sun, receiving varying amounts of direct solar radiation.
