- Moon is revolving around the earth
- Earth is revolving around its axis
- Earth is revolving around the sun
- Planet Mars is attracting the sun
- 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.
- Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays.
