Rotation
Define rotation
The spinning of the Earth on its axis.
Define revolution.
Revolution is the movement of the Earth around the Sun.
What two factors are responsible for the creation of the seasons?
The tilt of the Earth's axis and the revolution of the Earth around the Sun.
the relative positions of Earth, the Moon, and the Sun.
365 days and 1/4 day
March 21-23 (Spring Equinox) and September 21-21 (Fall Equinox) have the length of daylight and night time hours equal. True or False
28 days
How are waxing and waning different?
Waxing moon increases in visibility as seen from earth. Waning is when the moon decreases in visibility as seen from earth.
What is the tilt of the earth?
23.5 degrees
What is the speed of earth's revolution?
67,000 miles per hour
Why do we always see the same side of the moon.
The moon takes 28 days to rotate on its axis and 28 days to revolve around the Earth. As a result, we only see one side of the moon. (moon day = moon year)
Ocean tides are highest when there is a full moon because the Sun, Moon, and Earth are in alignment. True or False
TRUE
How long is 1 day (ie how long does it take for the earth to complete 1 rotation?)
23 hours and 56 minutes
What shape is the Earth's orbit.
Ellipse (or elliptical)
During which season is there the longest days? Why are days longest then?
Day length is the longest during the summer. Days are longest then because the Earth is tilted towards the Sun.
If today is a full moon, how many days until the next new moon?
14 days
What creates the tides on Earth?
Gravitational pull from the moon (and sun)
North pole tilts towards the sun, the Northern Hemishpere is experiencing what season?
Summer
Compare the Earth and Moon's revolutions. Include information about what they are revolving around and how long the revolution takes.
Earth: revolves around the Sun and it takes 365 days.
Moon: revolves around the Moon and it takes 28 days.
contrast the relative positions of the Sun, Earth, and Moon during the full moon phase and the new moon phase. (ie during which phase is the moon farthest vs closest to the sun)
During Full moon phase, the moon is farthest from the sun. During the new moon phase, the moon is nearest to the sun.
For the waxing phase of the moon, is the visible light coming in on the left or right hand side of the moon.
Right hand side
Ocean tides are highest when there is a full moon because the Sun, Moon, and Earth are in alignment.
As the Earth rotates on its axis, the moon exerts a gravitational pull on the Earth. The gravitational pull creates two tidal bulges on opposite sides of the Earth. When Earth turns on its axis, continental coastlines rotate in and out of the tidal bulges causing daily high and low tides.
