Seasons
Which season is characterized by colder temperatures, shorter days, and often includes snowfall?
Winter
How long does it take for the Earth to complete one full rotation on its axis?
24 hours
What is the primary reason we experience day and night on Earth?
Earth's rotation
The Northern Hemisphere experiences this when tilted towards the sun
Direct Sunlight
The spinning of the Earth once on its axis; gives us day and night
Rotation
What is the primary cause of seasons on Earth?
The Earth's tilted axis
What is the difference between the Earth's rotation and it's revolution?
Rotation = spinning on axis
Revolution = orbit around the sun
In which direction does the Earth rotate?
The Southern Hemisphere experiences this when the Northern Hemisphere is tilted towards the sun.
Indirect Sunlight
The motion of a body that travels around another body in space
Revolution
During which equinox do both the Northern and Southern Hemispheres experience equal day and night?
Spring and Fall
How long does it take for the Earth to complete one full revolution?
Where on Earth are sun rays the least direct?
North or South Pole
The Northern Hemisphere is experiencing this when the Southern Hemisphere is tilted towards the sun
Indirect Sunlight
The time it takes for one complete rotation of Earth
Day
How does the tilt of the Earth's axis change the length of days and nights throughout the year?
different parts get more sunlight at different times, making days longer in some seasons and shorter in others
Why do we have leap years?
Earth's revolution takes 365.25 days. We add an extra day (Feb. 29th) every 4 years to prevent the calendar from drifting out of sync
Where on Earth are sun rays most direct?
The equator
The Southern Hemisphere experiences this when the Northern Hemisphere is tilted away from the sun.
Direct Sunlight
The time it take for one complete revolution of Earth around the Sun
Year
In the Southern hemisphere, during which solstice does the Antarctic Circle experience continuous daylight?
June Solstice/Summer Solstice
If the Earth's rotation were to slow down, how might this affect the length of a day and night?
The days and nights would be longer.
The point at which the Sun is as far north or as far south in the sky as possible.
Solstice
When the sun is neither tilted towards or away from the sun, hemispheres experience this
An equinox
The period of time when there are equal amounts of sunlight in both the Northern and Southern Hemispheres
Equinox
