Our Planet: Our Planet is very special
We have a rare and unique area in our solar system
Our placement distance from the sun effects many things that allow for life on earth
![Page 3: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/3.jpg)
Our Planet Continued: One thing that is also unique about
Earth is its axis
Earth’s axis makes it have a specific tilt
This tilt effects the Earth in many ways, and creates many interesting celestial events
![Page 4: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/4.jpg)
Solstices: A Name One of these celestial events—
solstices
The word “solstice” is derived from the Latin “sol”=sun and “sistere”=to stand still
Thus the word “solstice” means “sun that stands still”
![Page 5: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/5.jpg)
Solstice: Causes One cause of planetary solstice is the
Earth’s distance from the sun Another is the tilt of the axis During a solstice the sun travels to its
apex in the sky, then back down—rather then in one motion
These apexes are both at the sun’s southernmost and northernmost extremes
![Page 6: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/6.jpg)
Solstice: Results• One of the results for solstices are the apparent “standing still” of the sun for a time
•Another result is, in some cultures, the solstices serve as markers for the season—in other cultures this falls in the middle of the seasons
![Page 7: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/7.jpg)
Solstice: When The First Is:
› Mid-Late June
The Second Is:
› Mid-Late December

Equinox: A Name
One of these celestial events—equinoxes
The word “equinox” is derived from the Latin “aequus”=equal and “nox”=night
Thus the word “equinox” means “an equal night”
![Page 9: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/9.jpg)
Equinox: Causes The tilt of the Earth’s axis is just right,
that when the sun hits the angle, it appears and is in perfect division
This is because the sun in shining on the axis point right above it
![Page 10: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/10.jpg)
Equinox: Results
The results of equinoxes is that there are equal nights on two sides of the equator
![Page 11: Solstices & Equinoxes](https://reader035.fdocuments.net/reader035/viewer/2022062310/568163c2550346895dd4e686/html5/thumbnails/11.jpg)
Equinox: When Mid-Late March Mid-Late September

Summary The tilt of the Earth effects many things
One of the things that it effects is the apparent apex of the sun in the sky—solstices
Another thing that it effects is the apparent “standing still” of the sun during equinoxes
Both these celestial occurrences have reasons for their cause and they both have results
In concert, these ideas help to give us a deeper understanding of the complexity and uniqueness of our world
