The diagram shows four phases of the moon as it revolves around Earth. A student builds a model based on this diagram. The student uses foam balls to represent the moon and Earth and a flashlight to represent the sun. The student should shine the flashlight on the model of Earth from Position -

Which of these locations on Earth experiences the least change in the number of daylight hours throughout the year?

• Equator

• North pole

• Tropic of Cancer

• Tropic of Capricorn

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

In November 2013, an object orbiting the sun seemed to disappear behind the sun. When a satellite did not detect the object, astronomers thought that the object had been destroyed when it passed close to the sun. However, when another satellite detected a small, bright object with a fan-shaped tail, astronomers proposed that the object was not destroyed. What type of object were astronomers most likely observing?

• a comet

• an asteroid

• a meteor

• a nebula

With the use of the Hubble Space Telescope, scientists recently discovered a giant runaway star. It is 90 times larger than the sun and is very hot and blue-white in color. Why does the sun appear to be brighter than this runaway star when viewed from Earth?

• The sun is a different color than the runaway star.

• The sun is older than the runaway star.

• The sun is closer to the Earth than the runaway star.

• The sun is made of different elements than the runaway star.

In July 1994 the comet Shoemaker-Levy 9 collided with the planet Jupiter, as scientists had predicted. To be able to accurately predict when a comet will collide with a planet, it is essential to understand -

• the composition of a planet's atmosphere

• the gravitational attraction that exists between all bodies

• the attraction of opposite poles of a magnet to each other

• the formation of comets
