What type of movement causes earths seasons?

Earth's seasons are primarily caused by its axial tilt and its orbit around the Sun. As Earth revolves around the Sun, different regions receive varying amounts of sunlight at different times of the year due to this tilt. This results in the changing seasons: summer occurs in the hemisphere tilted toward the Sun, while winter occurs in the hemisphere tilted away. The combination of axial tilt and orbital position leads to the seasonal variations in temperature and daylight.
