Geology Unit 1

  1. What will be the first question on Exam 1?
    Did you do your flashcards?
  2. During what time period were the first humans, including Neil Armstrong, exploring the surface of the moon?
    On July 20,1969 (Apollo 11), an American (Neil Armstrong) was the first human to walk on the moon. And this was only the third time that man had circled the moon.
  3. What was unique about astronaut Harrison "Jack" Schmidt walking on the moon?
    On December 1972, Schmidt was possibly the last person to land on the moon.
  4. What is the justification of having manned lunar rovers on the moon for exploration?
    The rovers are allowed a wide range of lunar exploration.
  5. Why did the US stop manned flights to the moon?
    The lack of interest by the American public.
  6. What percentage of the current US Budget is spend by NASA (National Aeronautics & Space Administration)
    For 2011, NASA's budget (18.6 billion) is at 0.5% of the total US budget.
  7. Name the planets of our solar system, in order from the sun.
    Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
  8. Which of the known solar system inner planets and moons have not been phographed by space probes? (thinking question)
  9. Considering all of the solar system planets, which is the only one without a true gaseous atmosphere?
  10. Compare the relative sizes of the planets Venus and Mars to that of Earth.
    Venus is the Earth size diameter, but only 0.8 of the Earth's mass. Mars is 1/2 size of Earth but only 1/10 of Earth's mass.
  11. What is the name of the most recent "lander or probe" exploring on the surface of Mars since 2012?
    There is one active US mobile probe-Opportunity that landed in 2004. the Spirit probe, on the opposite side of Mars ceased operations in 2010. the Phoenix Mars Lander (5/2008) was positioned near the Mars North Pole and discovered water ice below the Martian soil. The large Mars rover Curiosity arrived in August 2012.
  12. Compare the mass of Jupiter to all our other solar system planets and moons. (Common exam question) 

    Is larger (has more mass) than all other solar system planets combined; could be considered a failed star.
  13. Which planet is famous for its beautiful "rings"?
    Saturn. It's rings are 10 times larger and 95 times heavier than Earth.
  14. Neptune was discovered in 1846. Has Neptune made a complete orbit since its discovery?
    Neptune did it's recent complete orbit in 2011.
  15. Since the new definitions of June 2008, compare "Plutoids" to "dwarf planets". 
    Plutoids are large "heavenly bodies" beyond  the general orbit path of Neptune. Whereas Dwarf Planets are large "heavenly bodies"  within the orbit of Neptune. 
  16. How many space probes have already visited Pluto (thinking question)
    • None. The New Horizons Space Probe should reach Pluto in 2015 for our first close-up view of that demoted planet.
  17. Why was Pluto (and Eris?) reclassified?
    Soon there may well be more than 200 other classified Plutoids. This is why Pluto was reclassified!
  18. Approximately how many moons (orbiting solar system planets)have been discovered (nearest 50)?
    Our solar system of (8) planets probably have more than 165 moons.
  19. How many moons are there that orbit the four inner solar system rocky planets? (a thinking question)
    There are 3 planets in the inner planets.
  20. What is the name of the large Saturn moon that has a nitrogen-methane atmosphere and riverbeds that were created by methane rainfall runoffs?
