The beginning of autumn in North American is in September, but the beginning of autumn in South America is in March. The diagram shows a picture of the Earth, the sun, and the moon on one day in September and another in March. Why does autumn start in different months of the year in North America and South America?

• Earth's orbit around the sun is not a perfect circle.

• North America has a larger landmass than South America.

• The moon has a greater pull on South America than North America.

• Earth's axis has a 23.5 degree tilt.

Students in a science class in Marfa, Texas, made a poster with a diagram to represent seasonal change in the Northern hemisphere. Which statement best describes conditions for Earth at position 1 in the diagram?

• There are an equal number of hours of daylight and nighttime in the Northern hemisphere, and the north pole is tilted away from the Sun.

• The Northern hemisphere has the fewest hours of daylight, and the Earth's axis does not tilt at this position.

• There are an equal number of daylight and nighttime hours in this position because the Earth is not tilted in this position.

• The Northern hemisphere has the fewest hours of daylight, and the north pole is tilted away from the Sun.

Which of these changes would likely occur if the rate of Earth's rotation on its axis increased?

• The length of the seasons would be longer.

• The length of the seasons would be shorter.

• The length of a day would be shorter.

• The length of a day would be longer.

The model shows Earth is several positions relative to the sun. In which position is it winter in North America?

• Position 1, because North America receives the most sun.

• Position 2, because North America is tilted toward the sun.

• Position 3, because North America is parallel to the sun.

• Position 4, because North America is tilted away from the sun.
