Draw and describe the relative position of the Earth, Moon, and Sun during a spring tide.
Show Answer

14. 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.

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

16. 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.

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

26. 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

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

28. 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.

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

30. 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.

49. 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

50. 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.

51. 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

52. 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.

53. 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

54. 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.

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

62. 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.

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

66. 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.
