1 Earth & Moon Study Guide
Chapter 19 Earth & Moon Study Guide

2 1. Rotation is spinning of the earth on its axis

3 2. Orbit the Earth’s path around the sun

4 3. Revolution the movement of one object around another

5 4. Axis imaginary line that passes through the center of the earth and the North and South poles

6 5. Equinox equal night, when the sun is directly over the Equator

7 6. Solstice When the sun reaches its greatest distance North or South of the equator

8 7. Gravity A force that attracts all objects to each other

9 8. Newton’s First Law of Motion
an object at rest will stay at rest, and an object in motion will stay in motion until another force acts on it

10 9. Inertia The tendency of an object to resist a change in motion

11 10. Perigee point of the moon’s orbit CLOSEST to the earth

12 11. Apogee point of the moon’s orbit FARTHEST from the earth

13 12. Eclipse A partial or total blocking of an object in space

14 13. Tides the rise and fall of the oceans

15 14. Lunar Eclipse Type of eclipse that occurs when the earth is between the sun and the moon and occurs with a full moon

16 15. Solar Eclipse Type of eclipse that occurs when the Moon is directly between the Earth & the sun where it blocks sunlight

17 16. Moon Phases the shapes of the moon as seen from the earth

18 17. What are the effects of the earth’s tilt?
Seasons Different Length of day light hours

19 18. What is the relationship between the seasons in the north & south hemisphere?
Opposite Summer in Northern and Winter in Southern

20 19. Moon Phase Chart Means Left/ Right Comes Before Comes After Waxing
Growing RIGHT Full Moon NEW MOON Waning Shrinking Left New Moon FULL MOON

21 19. Moon Phase Chart pt. 2 Meaning Looks Like Crescent
A small sliver of the moon is showing Banana Gibbous More than ½ but less than full Lemon

22 20. What did Galileo see when he looked at the moon through the telescope
Maria-dark areas Craters-pits Highlands-mountains

23 21. What is the gravity of the moon compared to earth’s gravity?
1/6 of earth’s gravity

24 22. What is the difference between apogee & perigee?
Apogee-when moon is farthest from earth (APART) Perigee-when moon is closest to earth

25 23. Draw the earth on it’s tilt, and label the tilt.
23.50

26 24. Eclipse Chart Type SOLAR Lunar Earth’s Position Sun Earth Moon
Sun Moon Earth Sun Earth Moon Moon Phase NEW MOON FULL MOON What is happening MOON BLOCKS SUNLIGHT Moon is in Earth’s shadow

27 25. Tides Chart Tides Position Occurs… Water Level Spring
Straight Line New & Full Moon Very high and low tide NEAP 90 Degrees 1st & 3rd Quarter Moon Not very high tide

28 26. Solstice & Equinox Chart
Date First day of… Length of Day… Winter Solstice December 21 Winter Shortest Day Summer Solstice June 21 Summer Longest Day Autumnal Equinox September 22 (around 21) Fall Equal day & night Vernal Equinox March 21 Spring

29 27. Motion of Earth Chart Rotation REVOLUTION
Description Spinning of Earth on Axis One Object Moving around another Causes Days/Nights SEASONS & YEAR

30 28. What does the moon orbit?
The moon goes around the earth

31 29. What does Earth revolve around?
The earth revolves around the SUN

32 30. Why do we always see the same side of the moon?
It takes the same amount of time to rotate as it does to revolve

33 31. Moon Phases New Moon Waxing Crescent First Quarter Waxing Gibbous
Full Moon Waning Gibbous Third Quarter Waning Crescent

34 32. What are the effects of their being no atmosphere on the moon?
Extreme Temperature changes Many Craters

35 33. What part of the moon is visible during…
Percent Fraction a. 1st quarter? 25% ¼ b. Full Moon? 50% ½ C. 3rd Quarter? 25% ¼ D. New Moon? 0% 0/4 = 0

36 34. What part of the moon is not visible during…
Percent Fraction a. 1st quarter? 75% ¾ b. Full Moon? 50% ½ C. 3rd Quarter? 75% ¾ D. New Moon? 100% 4/4 = 1

37 35. On Earth, Barney weighed 250 pounds, with his suit and backpack on
35. On Earth, Barney weighed 250 pounds, with his suit and backpack on. Pluto’s gravitational pull is only 13% of Earth’s. How much did Barney weigh on Pluto? 13% x 250 = 32.5 pounds .13 x 250 = 32.5 pounds

38 36. A wave is 5 meters high during high tide and 1
36. A wave is 5 meters high during high tide and 1.7 meters high during low tide. How much higher are waves during high tide than low tide? 5 – 1.7 = 3.3 meters
