Earth-Sun-Moon

What is the average duration of daylight and darkness at the equator?

• Approximately 10 hours of daylight and 14 hours of darkness.

• Approximately 12 hours of daylight and 12 hours of darkness.

• Approximately 8 hours of daylight and 16 hours of darkness.

• Approximately 15 hours of daylight and 9 hours of darkness.

What is the relationship between Earth's rotation and the concept of time zones?

• Earth's rotation creates the cycle of day and night, leading to the establishment of time zones.

• Time zones are determined by the distance from the equator.

• Earth's rotation has no effect on time zones.

• Time zones are based solely on political boundaries.

What happens to the length of a day if Earth's rotation speed increases?

• The length of a day would be shorter.

• The length of a day would be longer.

• The length of a day would remain the same.

• The length of a day would vary unpredictably.

What movement of the Earth causes day and night?

• Rotation

• Revolution

• Tilt

• Orbit

What is the primary reason for the variation in daylight hours throughout the year?

• The distance of Earth from the Sun varies throughout the year.

• The tilt of Earth's axis and its orbit around the Sun.

• The rotation speed of the Earth changes with the seasons.

• The presence of clouds affects daylight hours.

What would happen to seasons if Earth's axis were at a 90° angle?

• No point on Earth would experience a change in seasons.

• Seasons would become more extreme with longer summers and winters.

• There would be no seasons at all, only constant weather.

• Seasons would occur every month instead of every three months.

What is the tilt of Earth's axis relative to its orbit?

• 22.0°

• 23.5°

• 24.5°

• 21.5°

What is the significance of the equinoxes?

• They are the times of the year when day and night are approximately equal in length.

• They mark the beginning of summer and winter.

• They are the longest days of the year.

• They indicate the changing of the seasons.

What is the term for the movement of Earth around the Sun?

• Rotation

• Revolution

• Orbiting

• Translation

How does the angle of Earth's tilt affect sunlight received at different latitudes?

• A greater tilt angle results in more direct sunlight at certain latitudes, affecting temperature and seasons.

• A smaller tilt angle leads to more uniform sunlight distribution across all latitudes.

• The angle of tilt has no effect on sunlight received at different latitudes.

• The tilt angle only affects the equator, not other latitudes.
