9. Eclipses A solar eclipse occurs when the Moon passes between the Earth and the Sun. Since the Moon and Sun appear to be the same size in the sky, the Moon can completely block the Sun if the relative positions of the Moon and the viewer are just right. Even though any place on Earth is subject to seeing an eclipse at one time or another, the area of the Earth which will perceive any particular eclipse as total is relatively small. The rest of the Earth will either see it as a partial eclipse, or will miss it altogether. A lunar eclipse occurs when the Earth passes between the Sun and the Moon. Since the Earth's shadow is larger than the Moon, the Moon can be completely blacked out. Actually, a total lunar eclipse rarely blacks out the Moon completely. Light refracted through the Earth's atmosphere into the shadow area will usually give it a strange dark red glow. The other difference from a solar eclipse is that every place on Earth that can see the Moon at the time of the eclipse will see more or less the same thing. - a solar eclipse will occur at the time of a New Moon - a lunar eclipse will occur at the time of a Full Moon

11. Notes Page -When the sun and moon are aligned, there are exceptionally strong gravitational forces, causing very high and very low tides which are called spring tides, though they have nothing to do with the season. -When the sun and moon are not aligned, the gravitational forces cancel each other out, and the tides are not as dramatically high and low. These are called neap tides. http://player.discoveryeducation.com/index.cfm?guidAssetId=77AC62FE-4AF5-4EC3- AD18- FD575CCBE388&blnFromSearch=1&productcode=US
