A-The rotation of the sun
B-The tilt of the Earth on its axis
C-The heating cooling of the sun
D-The rotation of the Earth on its axis

Answer 1

Answer: The Short Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
