The correct responses that describe how the tilt of Earth's axis and its movement around the Sun play a part in the changing of the seasons in the Northern Hemisphere are:
- Winter begins in the northern hemisphere when it's tilted away from the Sun.
- Seasonal change is caused by the tilt of each hemisphere relative to the sun as the Earth moves around the Sun.
- Summer begins in the northern hemisphere when it's tilted towards the Sun.
The other options are incorrect:
- The Moon's gravitational pull causes the change in seasons. (This is incorrect as the Moon's gravitational pull affects tides, not seasons.)
- The amount of sunlight the Southern Hemisphere receives directly affects the Northern Hemisphere's seasons. (This is misleading; each hemisphere experiences seasons independently.)
- The Earth's rotation speed determines the seasons. (Rotation does create day and night but does not change the seasons.)
- The Earth's orbit around the Moon influences the seasonal changes. (The Moon orbits Earth, not the other way around, and does not influence seasonal changes.)
