Which statement correctly explains which position of Earth represents summer in the United States?

• Position 1, because the Western Hemisphere is facing the Sun

• Position 2, because the Northern Hemisphere tilts toward the Sun

• Position 3, because Earth is at its closest point to the sun in its orbit

• Position 4, because Earth is traveling at its fastest rate in its orbit

• It is April in the Southern Hemisphere.

• It is summer in the Northern Hemisphere.

• The number of hours of daylight is greater in the Southern Hemisphere than in the Northern Hemisphere.

The beginning of autumn in North America is in September, but the beginning of autumn in South America is 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 on North America.

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 Earth’s axis does not tilt at this position.

• There are an equal number of hours of daylight and nighttime in the Northern Hemisphere because Earth’s axis 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 shorter.

• The length of the seasons would be longer.

• The length of a day would be shorter.

• The length of a day would be longer.

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

• Position 1, because North America receives the most direct 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
