Transcript of Day and Night

Vocabulary
axis- an imaginary line that runs through Earth from the North to South pole
rotate- To spin in one spot
orbit- To move around an object
sunrise- When the part of Earth you are located on rotates to face the sun
sunset- The end of daylight
horizon- line where the sky & earth's surface seem to meet
cycle- a certain set of events that happen multiple times
TO ORBIT AND ROTATE ARE COMPLETELY DIFFERENT DO NOT FORGET THAT!
Earth's Axis
Earth's axis runs through Earth from the North pole to the South pole. Earth, rotates on the axis.
Earth does one complete rotation about every 24 hours which is one day.
Rising and Setting
At sunrise, the part of the Earth you're located on rotates towards the sun. It looks like the sun is rising from the eastern horizon,
the sun

rises in the morning and keeps rising until it can go no higher at noon the sun starts to set.

But at sunset, the sun appears to set in the western horizon.

But actually the sun did not rise in the east and set in the west it looks that way because of Earth's rotation, this is called
apparent motion
Thank-you and if I missed anything it should be on this educational video that I could get thanks to Youtube.com

Day and Night
By; Cadence Harvey

Daytime and Nighttime
Earth sits on it's axis at an angle of 23.5 degrees. Every moment of the day half of earth is facing the sun. That part of the Earth gets light and more heat from the sun, and for them it is daytime. The other half of the world that is not facing the sun doesn't get light or as much heat from the sun, therefor it is nighttime.
Orbiting and Rotating
Earth orbits around the sun. While earth orbits, it is rotating in circles at the same time. It takes one full year to complete one full orbit around the sun. Earth's tilted axis and orbiting around the sun cause seasons to change. The Earth orbits around the sun, and the moon orbits the Earth.
Example:
like if you were a park and
t
here is a Merry-Go-Around, and you decided to ride it when you are spinning on it, if you open your eyes it looks like the park is spinning around you like how the sun looks like it rises in the east moves across the sky and sets in the west but really it is just you (A.K.A THE EARTH) rotating in circles. And the same thing happens over and over again which is the day and night cycle
Thank you for listening!

Here is a video from youtube,

look at the outside of the merry-go-round,notice how even in freeze frame it still looks like the outside is moving, but really it is just you rotating.
