8 Question for 5 Points An _______ occurs when the moon’s shadow hits Earth or Earth’s Shadow hits the moon. Show Answer

9 Answer for 5 Points Eclipse Back to Board

10 Question for 10 Points ___________ is the path of Earth as it revolves around the sun. Show Answer

11 Answer for 10 Points Orbit Back to Board

12 Question for 15 Points A _____ tide occurs when the sun is at right angles to the line between Earth and the moon Show Answer

13 Answer for 15 Points Neap Back to Board

14 Question for 20 Points Draw and describe the relative position of the Earth, Moon, and Sun during a spring tide. Show Answer

15 Answer for 20 Points During spring tides, the Sun, Earth, and Moon are aligned in a straight line. This requires the moon phase to be new or full. Back to Board

16 Question for 25 Points Why do we observe moon phases on Earth? Show Answer

17 Answer for 25 Points As the Moon rotates around the Earth (once every 29.5 days), the portion of the Moon that reflects sunlight back to Earth changes. Thus, the Moon goes through a lunar cycle about once every calendar month. Back to Board

18 Question for 30 Points Draw one complete cycle from new Moon to new Moon showing the relative position of the Earth, Sun, and Moon in your drawing. Show Answer

19 Answer for 30 Points Back to Board

20 Question for 5 Points Differences in the moon’s and sun’s pul on different sides of Earth cause ______. Show Answer

21 Answer for 5 Points tides Back to Board

22 Question for 10 Points A person standing in the moon’s _________ would see a partial solar eclipse. Show Answer

23 Answer for 10 Points prenumbra Back to Board

24 Question for 15 Points When the sun is farthest north or south of the equator it is called a ___________________. Show Answer

25 Answer for 15 Points Solstice Back to Board

26 Question for 20 Points Why don’t we see eclipses Monthly? Show Answer

27 Answer for 20 Points One might expect to see eclipses monthly, as the Moon moves through its lunar phases. However, since the Moon’s orbit around the Earth is tilted at about 5 degrees (relative to the Earth’s orbit around the Sun), the tilt is enough to keep the moon out of Earth’s shadow for most full moons and out of the Moon’s shadow for most new moons. Thus, eclipses, especially total eclipses, are rare events Back to Board

28 Question for 25 Points What causes the Earth to experience high and low tides daily? Show Answer

29 Answer for 25 Points Tides on Earth are primarily affected by the Moon’s gravity. As the Earth rotates on its axis, a given location’s distance from the moon fluctuates, and therefore the gravitational attraction between the Earth and Moon change as well, which result in tidal bulges at the locations under the greatest gravitational attraction (high tide). Since the amount of water in the ocean is relatively constant, the areas not in the tidal bulge experience low tide. Back to Board

30 Question for 30 Points Why are the seasons opposite in the Northern and Southern Hemispheres? Show Answer

31 Answer for 30 Points Since the Earth rotates on an axis that is tilted 23.5 degrees as it revolves around the Sun, the Northern and Southern Hemispheres cannot both be tilted towards the Sun at the same time. Back to Board

32 Question for 5 Points Imaginary line passing through Earth’s center and poles is called an _______. Show Answer

33 Answer for 5 Points axis Back to Board

34 Question for 10 Points A _______ eclipse occurs at a full moon when Earth is directly between the moon and the sun. Show Answer

35 Answer for 10 Points Lunar Back to Board

36 Question for 15 Points A _________ tide occurs when the sun, Earth and the moon are nearly in a line. Show Answer

37 Answer for 15 Points Spring Back to Board

38 Question for 20 Points How are moon phases associated with solar and lunar eclipses? Show Answer

39 Answer for 20 Points Solar eclipses are associated with a new moon, and lunar eclipses are associated with a full moon. Back to Board

40 Question for 25 Points Draw a picture that depicts the position of the Moon and Earth during a low tide. Show Answer

41 Answer for 25 Points Back to Board

42 Question for 30 Points With respect to the Northern Hemisphere, what is the relative position of the Earth and Sun in summer, autumn, winter, and spring? Show Answer

43 Answer for 30 Points Back to Board

44 Question for 5 Points The term use when the noon sun is directly overhead at the equator Show Answer

45 Answer for 5 Points equinox Back to Board

46 Question for 10 Points The movement of Earth around the sun Show Answer

47 Answer for 10 Points revolution Back to Board

48 Question for 15 Points Name all the phases of the moon in order starting at new moon. Show Answer

49 Answer for 15 Points New Moon Waxing Crescent First Quarter Waxing Gibbous Full Moon Waning Gibbous Third Quarter Waning Crescent Back to Board

50 Question for 20 Points What conditions are necessary for a lunar eclipse to occur? Draw and describe the relative position of the Earth, Moon, and Sun during a lunar eclipse. Show Answer

51 Answer for 20 Points Eclipses are events during which one object in space casts a shadow onto another. In the case of a lunar eclipse, the Moon is either entirely obscured (total lunar eclipse)or partially obscured (partial lunar eclipse), as the Earth is directly between the Moon and the Sun, and the shadow of the Earth falls on the Moon. In order for a lunar eclipse to occur, the moon phase must be full. Back to Board

52 Question for 25 Points What causes the Earth to experience spring and neap tides on a bi-monthly basis? How do moon phases influence this? Show Answer

53 Answer for 25 Points Spring tides are extreme high tides. Neap tides are extreme low tides. Spring and neap tides are experienced due to the added positive (spring tide) or negative (neap tide) influence of the Sun’s gravity when the Sun, Earth, and moon are aligned (spring tide) or at a ninety degree angle (neap tide). Spring tides require a full or new moon, and thus occur bi-monthly. Neap tides require a first or third quarter moon, and thus occur bi-monthly. Back to Board

54 Question for 30 Points Explain how the angle the sunlight reaches the Earth impacts the number of hours of sunlight and average temperatures. Show Answer

55 Answer for 30 Points Areas tilted towards the Sun with the sunlight striking at a more direct angle experience longer days and warmer temperatures than areas tilted away from the Sun with sunlight striking at a less direct angle. The equator, which receives sunlight at a more direct angle, has about 12 hours of night and day and does not experience much fluctuation in temperature. The poles receive sunlight at a less direct angle than at the equator, and therefore tend to be cooler year-round. However, in the summer and winter, the poles have nearly 24 hours of sunlight or darkness depending on if its hemisphere is tilted towards or away from the Sun. Back to Board

56 Question for 5 Points Movement of Earth around its axis Show Answer

57 Answer for 5 Points Rotation Back to Board

58 Question for 10 Points A person standing in the moon’s ________ would see a total solar eclipse. Show Answer

59 Answer for 10 Points Umbra Back to Board

60 Question for 15 Points A ______ eclipse occurs when the moon passes between Earth and the sun Show Answer

61 Answer for 15 Points Solar Back to Board

62 Question for 20 Points What conditions are necessary for a solar eclipse to occur? Draw and describe the relative position of the Earth, Moon, and Sun during a solar eclipse. Show Answer

63 Answer for 20 Points Eclipses are events during which one object in space casts a shadow onto another. In the case of a solar eclipse, the Sun is either entirely obscured (total solar eclipse) or partially obscured (partial solar eclipse), as the Moon is directly between the Sun and Earth, and the shadow of the Moon falls on part of the Earth. In order for a solar eclipse to occur, the moon phase must be new. Back to Board

64 Question for 25 Points Draw and describe the relative position of the Earth, Moon, and Sun during a neap tide. Show Answer

65 Answer for 25 Points During neap tides, the Sun, Earth, and Moon are at a ninety degree angle. This requires the moon to be first quarter or third quarter Back to Board

66 Question for 30 Points What causes the Earth to experience seasons? Show Answer

67 Answer for 30 Points Seasons are experienced on Earth due to changes in the intensity of sunlight (angle sunlight strikes that part of Earth due to its spherical shape) and the number of daylight hours, which result from the Earth’s rotation on a tilted axis as it revolves around the Sun.
