1. Earth / Moon Relationships Tides, Eclipses, Phases, & Formation

2. Rotating & Revolving Rotating –The spinning of a planet, moon, sun or other object on its axis. Revolving –The orbital path of a space object as it moves around another.

4. Earth Revolves around the Sun

5. Phases of the Moon < New < Waxing Crescent < First Quarter < Waxing Gibbous < Full < Waning Gibbous < Third Quarter < Waning Crescent

7. Tides –Daily rise and fall of the Earth’s waters caused by the gravitational pull of the moon and sun.

8. Tides Spring –When the sun and the moon are aligned the pull is greater on the earth, thus a greater tide.

9. Tides Spring Neap –When the sun and moon are at right angles to each other their pull is counteracted creating lower tides.

11. Eclipses Solar Eclipse –The Moon passes between the Earth and the Sun casting a shadow on the Earth.

12. Eclipses Solar Eclipse Lunar Eclipse –During a Full Moon the shadow of the Earth can then be seen cast onto the Moon.

13. Eclipses Umbra –The area of shadow that creates a total eclipse. Penumbra –The area of shadow that creates a partial eclipse.

14. Eclipses Umbra –The area of shadow that creates a total eclipse. Penumbra –The area of shadow that creates a partial eclipse.

15. Moon Formation The Fission Theory: –The Moon was once part of the Earth and somehow separated from the Earth. The Capture Theory: –The Moon was formed somewhere else, and was later captured by the gravitational field of the Earth. The Condensation Theory: –The Moon and the Earth condensed together from the original nebula that formed the Solar System. The Colliding Planetesimals Theory: –The interaction of very large chunks of rocks like asteroids condensed to from the Moon. The Ejected Ring Theory: –A planetesimal the size of Mars struck the earth, ejecting large volumes of matter. A disk eventually condensed to form the Moon. Formation Video
