If you wanted to make all days on Earth the same length, what would you have to do? A) Keep the Earth from tilting on its axis B) Increase the speed of the Earth’s rotation. C) Tilt the Northern Hemisphere all the way toward the Sun. D) Tilt the Southern Hemisphere all the way toward the Sun. 3. A meteorite is DIFFERENT from a comet mainly because it A)has a tail of ice and dust. B)enters the Earth’s atmosphere. C)has a nucleus made of snow and rock.D)is found in orbit between Mars and Jupiter. 4.The tail of a comet usually faces A) toward the Sun. B) away from the Sun C) toward the Earth. D) away from the Earth. 5.When the Sun is completely blocked out by the Moon a ________________ occurs. A) total solar eclipse B) total lunar eclipse C) partial solar eclipse D. partial lunar eclipse 6. If the earth were not tilted on its axis, what would be the result? A. Day length would be less than 24 hours. B) Both sides of the moon would be visible. C) Temperatures would be constant year round. D ) The length of the year would be more than 365 days. 7.The Northern Hemisphere is warmer in spring than in winter, because in spring A) the days are shorter. B) it gets more direct sunlight. C) the Earth is closer to the Sun. D) it is tilted away from the Sun. 8. During which season do the rays of the sun hit the Earth at the MOST indirect angle? A) fall B) spring C) summer D) winter C)Cosmic background X-ray radiation was detected in space. D)The existence of common elements throughout the universe. 6.Looking through his telescope, Galileo observed that Jupiter had a set of moons, much like Earth does. The moons revolved around the planet. This disproved the idea that all objects in space revolved around Earth. This means that A)scientific knowledge is almost always incorrect. B)scientific knowledge began only after the telescope was invented. C)scientific knowledge can be revised if better evidence comes to light. D)scientific knowledge can only be gained by using sophisticated instruments. 7.Edwin Hubble is credited for the initial 9. As Earth spins on its axis, producing night and day, it also moves about the Sun in an elliptical orbit that requires about 365 1/4 days to complete. The Earth's axis is tilted with respect to its orbital plane. When the earth's axis points towards the sun, it is __________ for that hemisphere. A) day B) night C) summer D) winter 10.

Which piece of evidence did Hubble find that led him to begin the development of the Big Bang theory? A)The sun is the center of the universe. B)The universe is expanding in all directions. C)New universes are being made on a regular basis. D)All life appeared on earth about 3.5 billion years ago. 8.The universe cooled after the Big Bang.

Yet you and I can see Venus with the naked eye, and definitely with a pair of binoculars. But for us to see Neptune, we would need a strong telescope. This is because A)Neptune is on the opposite side of the sun B) of our position on the surface of the Earth. C) most of Neptune's mass is gas and we cannot see gas. D )Neptune is so far from Earth and Venus is much closer. 8. Why does Earth orbit the Sun rather than any other body in the solar system?

D)The rotational motions of all the planets, including Earth, cause them to remain in its orbit around the Sun. 9.Hundreds of years ago, it was believed by many that our solar system was Geocentric. This means that Earth is at the center of the solar system, with the Sun and other planets orbit around it. Today, the solar system is now thought to be Heliocentric. What does this mean? A)The Sun and other planets orbit Earth. B)Earth and all the other planets orbit the Sun. C)The other planets orbit Earth, and Earth orbits the Sun. D)The Sun orbits Earth and the other planets orbit the Sun. USA Test Prep Grade_________ 6. Which lunar phase would be observed from the Earth, if the moon were at a 90° angle with the earth and sun?

Although they occur somewhere on Earth every 18 months on average, it is estimated that they recur at any given place only once every 370 years. Why are reoccurring solar eclipses so rare? A) Because of the rotation of the moon and earth, the three rarely form a straight line. B) The light from the sun usually passes through the moon instead of being blocked by it. C) A total solar eclipse actually occurs monthly, but is only visible from the the equator. D )The Moon passes slightly above or below the line between the Sun and the Earth because of its tilted orbit. 8Approximately what percent of the Moon’s surface is illuminated on a new-moon day?
