BIG IDEA: The changing positions of the moon, Earth, and sun cause the phases of the moon,
tides, and eclipses!!

The rock sphere that travels around Earth. Rotates and Revolves.
◦ At the same speed!

Different shapes of the moon as seen from Earth.
The moon Does Not give off its own light!!!◦ it only reflects light from the sun.
As the moon revolves around Earth, we observe different amounts of its lighted surface.

Moon Terms◦Waxing-when the moon appears to be growing
in the sky. ◦Waning-when the moon appears to be
shrinking in the sky.◦Crescent-when the moon appears to be a sliver
in the sky. ◦Gibbous-when more than half the moon
appears in the sky.

The rise and fall of ocean waters twice a day.
Caused by the gravitational pull of the moon and the gravitational pull of the sun.

The moon’s gravity pulls the oceans into two bulges, one facing the moon and the other on the opposite side of Earth.

Spring Tides◦ Gravity from the sun and moon combine to form
the largest high tides.

Neap Tides◦ Sun and moon’s gravity go against each other
perpendicularly to form the smallest high tides.

When the sun, Earth, and moon line up and cast a shadow on one another.

Solar Eclipse◦ The Moon casts a shadow on the Earth.◦ Occurs during a new moon.
![Page 14: BIG IDEA: The changing positions of the moon, Earth, and sun cause the phases of the moon, tides, and eclipses!!](https://reader035.fdocuments.in/reader035/viewer/2022062518/56649e845503460f94b8581c/html5/thumbnails/14.jpg)
Lunar Eclipse◦ Earth’s shadow is cast upon the moon. ◦ Occurs during a full moon.
![Page 15: BIG IDEA: The changing positions of the moon, Earth, and sun cause the phases of the moon, tides, and eclipses!!](https://reader035.fdocuments.in/reader035/viewer/2022062518/56649e845503460f94b8581c/html5/thumbnails/15.jpg)
Total solar eclipse◦ The moon casts two shadows on the Earth.
Penumbra-the partial shadow of the moon. Umbra-complete shadow of the moon.
◦ Under the Umbra, the entire sun is blocked out, it appears to be night. (total solar eclipse).

Total Lunar Eclipse◦ When the moon falls into Earth’s umbra.◦ Much more common than solar eclipses.
