The diagram shows Earth in its orbit around the sun when very little light is visible at Earth's South Pole.

  

Which TWO statements are true when Earth is in the position shown?

• It is August in the Northern Hemisphere.

• It is April in the Southern Hemisphere.

• It is summer in the Northern Hemisphere.

• It is winter in the Southern Hemisphere.

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

The model shows Earth in four different positions in its orbit around the sun. 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

The diagram shows Earth in its orbit around the sun when very little light is visible at Earth’s South Pole. Which statement is true when Earth is in the position shown?

• It is summer in the Northern Hemisphere. It is winter in the Southern Hemisphere.

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

• Spring begins earlier in the year in the Southern Hemisphere than it does in the Northern Hemisphere

Students make a model using a globe and a flashlight.

Which answer choice best explains the change from daytime to nighttime on Earth?

• The sun stops sending light to Earth at night.

• Earth moves farther away from the sun at night.

• The tilt of Earth causes less light to reach Earth at night.

• Earth rotates and causes different parts of Earth to experience night.
