Earth Moon And Sun Jeopardy Template

Tides and Moon Phases	Seasons	Elliptical Orbit	Rotation and Revolution	Eclipses
100 The moon's gravity. What causes tides?	100 The changes in the intensity of sunlight and the tilt of the Earth’s axis. Why do we experience seasons?	100 The objects in space don't follow an exactly round pattern around the sun. Instead, their paths are oval-shaped. Do objects follow perfectly round orbits around the sun? If not, what shape is their orbit?	100 Rotation is when something spins on its axis. Revolution is when something circles around another object. What is the difference between rotation and revolution?	100 They occur when the Earth's shadow blocks the moon or the moon's shadow blocks part of the Earth. When do eclipses occur?
200 True True/False- We always see the same side of the moon.	200 Equinoxes are when there are equal amount of daylight and darkness; Solstices are when it is the longest or shortest day of the year. What is the difference between equinox’s and solstices?	200 The aphelion is the point where the object is farthest away from the sun, whereas the perihelion is the point where the object is closest. What is the aphelion and the perihelion and how are they different?	200 24 hours (1 day) How long does it take to complete a rotation?	200 The moon is slanted slightly, at a five degree angle, so we don't get an eclipse every month. Why doesn't an eclipse occur every month?
300 The Earth, Moon, and Sun have to be in a straight line. What has to happen in order for a spring tide to occur?	300 Seasons change because of the tilt on the axis, when the northern hemisphere is tilted closer to the sun, it is summer and there are longer days, on the Southern Hemisphere it is winter and there are shorter days. How does the tilt of the Earth’s axis affect the temperature and daylight hours of a location on earth?	300 They take hundreds of years because their paths are so elliptical. How many years do long-distant comets (that originate in the Oort cloud) take to orbit around the sun and why?	300 365 1/4 days How long does it take to complete a revolution?	300 Solar eclipses (moon blocks sun) and Lunar eclipses (earth blocks moon). What are the two main types of eclipses?
400 Smaller If the moon is waning, is the lit side of the moon getting smaller or bigger?	400 June What month does winter begin in the Southern Hemisphere?	400 Gravity. What causes elliptical orbits?	400 A revolution take 365 1/4 days so instead of having a fourth of a day we have one extra day every four years. Why do leap years occur?	400 The umbra is the darkest part of the moon's shadow, and it only a very small portion of the earth is covered by it whereas the penumbra is the wider, less dark portion of the shadow that covers more of the Earth. What is the umbra and the penumbra of the moon and how are they different?
500 Neap tide What type of tide occurs when the Earth, Moon, and Sun form a 90 degree angle?	500 The equator Where does Earth’s temperatures and daylight hours stay the most constant?	500 No, the orbit of the Earth is nearly circular, so the distance to the sun does not have a large impact on the seasons. Does the elliptical orbit of the Earth affect the seasons?	500 The invisible pole that runs through the north and south that the earth spins on. Define axis	500 A lunar eclipse happens when the earth passes between the sun and the moon when the moon is in its full moon phase. When does a Lunar eclipse happen?
