Two students drew a model representing why we have "day" and "night" on Earth. Which student has the correct model?
Student A
Student B
Both are correct
Our Earth cycles through day and night regularly. This cycle allows us to have a way to keep track of time and schedule our daily lives. Most of our activities and interactions occur during the day and most of our sleeping occurs at night. Without a regular day and night cycle, people's schedules would be quite different from one another.
The day and night cycle is the length of time it takes the Earth to rotate one time.
On Earth, one day and night cycle is 24 hours long.
The sun appears to rise from the same direction and set in the same direction daily.
The day and night cycle allowed people to be able to tell time before clocks were invented.
Which of the following best describes why we experience day and night?
The Earth orbits around the Sun
The Moon blocks the Sun's light
The Earth rotates on its axis
The Sun moves around the Earth
The earth rotates around it's axis over
12 hours
24 hours
365 days
30 days
