Seasons and Earth's Tilted Orbit

What is the primary reason for the change in seasons on Earth?

• The distance between the Earth and the Sun changes.

• The tilt of the Earth's axis as it revolves around the Sun.

• The rotation of the Earth on its axis.

• The shape of the Earth's orbit around the Sun.

Which of the following best describes the Earth's axis?

• A line that runs from the North Pole to the South Pole.

• A line that runs from the equator to the Sun.

• A line that runs parallel to the Earth's orbit.

• A line that runs from the East to the West.

Explain how the tilt of the Earth's axis affects the length of daylight during different seasons.

• The tilt causes the Sun to be higher in the sky during summer, resulting in longer days.

• The tilt causes the Earth to move faster in its orbit, resulting in longer days.

• The tilt causes the Sun to be lower in the sky during summer, resulting in shorter days.

• The tilt has no effect on the length of daylight.

Illustrate how the Earth's tilt and orbit cause the variation in daylight hours throughout the year.

• The tilt causes the Sun to rise and set at different times.

• The orbit causes the Earth to spin faster, changing daylight hours.

• The tilt and orbit have no effect on daylight hours.

• The tilt causes the Sun to be visible for different lengths of time.
