The tilt of the Earth's rotational axis toward or away from the sun causes ____.

Because of Earth's axial tilt, different areas of Earth point toward or away from the Sun at different times of the year. In June, the North Pole is tilted toward the Sun and the Northern Hemisphere receives more of the Sun's direct rays. At the same time, the South Pole points away from the Sun, creating winter in the Southern Hemisphere during the months of June, July and August.
