1 TIDES Earth and Moon Interaction The Earth is pulled to the Sun by gravity. The moon is pulled to the Earth by gravity. The moon s gravity effects the Earth s tides. Neap Tides A tide just after the first or third quarters of the moon There is the least difference between high and low water Spring Tides A tide just after a new or full moon There is the greatest difference between high and low water Forces that Influence the Tides Gravitational pull of the moon on the oceans (as shown above) Centrifugal force on the ocean a result of earth orbiting around the center of gravity between it and the moon Earth s rotation LUNAR CYCLE

GOAL: IDENTIFY THE PHASES OF THE MOON, AND RELATE THE PHASES TO ECLIPSES. Remember: white on the right, growing bright!

This means that when the white of the moon is on the right side, it is growing, but when it is on the left, it is decreasing.

2 GOAL: IDENTIFY THE PHASES OF THE MOON, AND RELATE THE PHASES TO ECLIPSES. Remember: white on the right, growing bright! White on the left losing light. This means that when the white of the moon is on the right side, it is growing, but when it is on the left, it is decreasing. Vocabulary Wax on increasing light this term is used when the moon is growing, just like you put more wax on a candle to make it bigger. Wane off decreasing light Gibbous bulge New Moon Near the Sun Full Moon Far from the Sun Watch this video for more information New moon moon between sun and earth not visible Possible solar eclipse, but does not happen every month because the orbit of the Moon is in a different plane than the Earth View from Earth of the moon during new moon

3 Waxing Crescent second moon phase Waxing means increasing in size (refers to the lit portion of the moon); crescent refers to the shape of the lit area View from Earth of the moon during waxing crescent First Quarter Moon has gone 1/4 of the way around the Earth From our point of view, the right half of the Moon is lit View from Earth of the moon during first quarter Waxing Gibbous Moon looks like a fat football Gibbous means bulging; during the waxing gibbous phase, the lit side of the Moon contiues to grow View from Earth of the moon during waxing gibbous Full Moon light is reflecting from the entire surface of the moon facing the Earth During this phase, it is possible to have a lunar eclipse View from Earth of the moon during full moon

4 Waning Gibbous waning means decrease in size Science side During this phase, the Moon s lit portion decreases in size; lit on the left View from Earth of the moon during waning gibbous Third Quarter lit side on the left Moon is three fourths of the way around its orbit View from Earth of the moon during third quarter Waning Crescent Moon cresent that gets smaller and smaller until the Moon completes its orbit and begins a new cycle with another new moon View from Earth of the moon during waning crescent Solar Eclipse Moon moves directly between Sun and Earth Moon casts a shadow on the Earth; occurs only with a new moon. Does not happen every new moon because the moon is often on a different plane of orbit than the Earth. Lunar Eclipse Earth, Sun, and Moon are directly lined up with the Earth in the middle. The Earth casts a shadow on the Moon; this only occurs during a full moon, but not most full moons because the moon is usually on a different plane of orbit than the Earth.

5 This is an example of the Sun, Earth, and Moon during a neap tide.

6 This is an example of the Sun, Earth, and Moon during a spring tide. Spring tides have higher high tides and lower low tides when the moon, sun, and earth are aligned in a row. This occurs because the gravitational pull is stronger. For most places on earth, the time difference between the two low tides are about 12 hours.

Term Info Picture. A celestial body that orbits a bigger celestial body (a moon) Earth s only natural satellite. It causes all of the tides.
