1. Earth - labeled on the planet in the center of the orbit
Moon - labeled on the smaller body orbiting the Earth
Sun - labeled on the large body at the center of the solar system
Revolution - labeled on the large arrow showing the Earth's orbit around the Sun
Rotation - labeled on the small arrows showing the Earth spinning on its axis
Orbit - labeled on the path the Earth follows around the Sun
Axis - labeled on the line through the Earth showing its tilt
2. The movement of revolution is the Earth's orbit around the Sun.
3. The Earth takes 365.25 days in its movement of revolution.
4. Every 4 years, the month of February has 29 days because of the leap year. This extra day compensates for the extra quarter day in the Earth's revolution period. The year with 366 days is called a leap year.
5. The two causes of the seasons are the tilt of the Earth's axis and its revolution around the Sun.
6. Each season lasts approximately 3 months.
7. The four stations are not distinguishable in the regions near the equator.
8. The reason for this is that the equatorial regions receive consistent sunlight throughout the year, resulting in little variation in temperature and weather patterns.
9. The name of the two times of the year when day and night have the same duration is the equinoxes.
10. The name of the two times of the year when there is a greater difference in the duration of day and night is the solstices.
