  1. The Earth's Moon Review

  2. I was the first man to set foot on the moon, I am _______________. Neil Armstrong

  3. The word lunar comes from the Latin word for ________________. Moon

  4. Armstrong and ____________left the Module Eagle to explore the moon. Edwin "Buzz" Aldrin

  5. Scientists learned more about the moon from the ________missions that ended in 1972 than they had learned in many years. Apollo

  6. The moon is about ______ the diameter of Earth. 1/4

  7. The moon’s gravity is ______ than that of the Earths. 1/6 less

  8. Objects weigh __________on the moon than they do on Earth. less

  9. If you weighed 120 lbs on Earth then you’d weigh _____lbs on the Moon. 20 lbs (120 divided by 6)

  10. If you weighed 240 lbs on Earth then you’d weigh _____lbs on the Moon. 40 lbs

  11. If something weighed 80 lbs on the Moon then it would weigh _____lbs on the Earth. 480

  12. If something weighed 25 lbs on the Moon then it would weigh _____lbs on the Earth. 150

  13. How did scientists begin to estimate the average distance to the moon? They left a small mirror on the moon.

  14. What purpose did leaving the mirror on the moon serve? A beam of light was bounced from the Earth off the mirror that was on the moon. They measured the amount of time it took the beam to bounce back to the Earth. Then using the speed of light, they could then calculate the distance to the moon accurately. A Beam of light was bounced fro the Earth off the mirror. They measured the amount of time it took the beam to bounce back to the Earth.

  15. Astronauts also brought back samples of _________________. moon rocks

  16. The oldest moon rocks are about _______billion years old. 4.6....about the same age as Earth!

  17. The moon does not have any ____________, therefore there is no weather on the moon. atmosphere

  18. The days can be warm on the moon (100 degrees C) and the nights very cold (-175 degrees C)!

  19. In 1609, ____________ became the first person to look at the moon through a telescope. He saw light and dark areas on the moon! Galileo Galilei

  20. The light areas Galilei saw are mountain ranges called ____________. Highlands

  21. The dark areas Galilei saw are broad, smooth, lowland plains called Maria

  22. Maria is the Latin word for ______. Seas

  23. _______________was also a famous Polish scientist/astronomer who first stated the theory that Earth and other planets revolve around the sun. Nicholas Copernicus

  24. Most of the Moon’s craters are located in the ___________. Highlands

  25. Evidence that the moon once had active volcanoes may be the long valleys that cross the Moon’s surface also known as _________. Rilles

  26. Another explanation that the rilles may be cracks caused by________. moonquakes

  27. The The moon revolves around the Earth a (n) ___________orbit. elliptical

  28. At _________________, the point of the moon’s orbit is closest to the Earth. (About 350,000 kilometers) Perigee

  29. v At _________________, the point of the moon’s orbit is farthest from the Earth. (About 400,000 kilometers away) Apogee

  30. The Moon takes _______to rotate once on its axis. 27.3 Days Almost a month!

  31. The Moon takes _______to revolve around the Earth. 27.3 Days This means that a day on the moon is just as long as a year on the moon!

  32. About 4.6 billion years ago a lot of space debris was floating around our Solar system. A giant asteroid (the size of Mars) hit the Earth and tore a chunk out of Earth’s surface. The pieces that flew off is now our moon (the pieces merged together in orbit due to Earth’s Gravity.) **The hole that was left on Earth is now the Pacific Ocean. **This is also supported by moon rocks. What is the theory of how the moon was created?

  33. The End (for now...)
