    • The scientists discovered water along with volatile elements in lunar magma trapped inside of crystals that aretrapped inside of tiny volcanic glass beads returned to Earth by Apollo 17. The discovery, published in the May26 Science Express, challenges assumptions of how the moon formed and the origin of frozen water at the lunarpoles. "These samples provide the best window we have to the amount of water in the interior of the Moon," saidJames Van Orman, professor of geological sciences at Case Western Reserve and an author of the paper. "Theinterior seems to be pretty similar to the interior of the Earth, from what we know about water abundance." Infact, the researchers found the concentrations of water and volatile elements including fluorine, chlorine andsulfur in lunar magma are nearly identical to concentrations in solidified magma from primitive terrestrial mid-ocean ridges on Earth. The discovery strengthens the theory that the moon and Earth have a common origin butforces scientists to reconsider the current theory of the process: that a huge impact in Earths early historyejected material into orbit that became the moon. Part of the origin theory says that water and other volatileelements and compounds were depleted due to the heat and violence of the impact. This research indicatesotherwise and provides new clues to the process of lunar formation.
    • The moon is about 238,900 miles (384,000 km) from Earth on average. At its closest approach (the lunarperigee) the moon is 221,460 miles (356,410 km) from the Earth. At its farthest approach (its apogee) themoon is 252,700 miles (406,700 km) from the Earth.The moon revolves around the Earth in about one month (27 days 8 hours). It rotates around its own axis in thesame amount of time. The same side of the moon always faces the Earth; it is in a synchronous rotation with theEarth.The Moons orbit is expanding over time as it slows down (the Earth is also slowing down as it loses energy). Forexample, a billion years ago, the Moon was much closer to the Earth (roughly 200,000 kilometers) and took only20 days to orbit the Earth. Also, one Earth day was about 18 hours long (instead of our 24 hour day). The tideson Earth were also much stronger since the moon was closer to the Earth.
    • This Diagram shows us the movement of the Moon in our planet
    • The New moon is when the moon is all dark. None of the moon that we can see is lit up duringthe new moon.A Crescent moon is when the moon is between the new and quarter moon stages. It looks likea "C" shape.The Quarter moon is when half of the moon is visible. If the moon is waxing, it is calledthe first quarter, if the moon is waning, it is the last quarterA Gibbous moon is between the quarter and full moon stages. More than half of the moon canbe seen, but not all of it.The Full moon is when the moon is all lit up. All of the moon that we can see is lit up by theSun during the full moon.A second full moon in one calendar month is usually called a blue moon. The saying "Once in ablue moon" refers to something that does not happen often - like a blue moon.[1][2]There are 8 moon phases.
    • Waxing is when the part of the moonthat we can see gets bigger everynight. It waxes until it is a full moon.Waning is when the moon appears tobe getting smaller in size every night.It wanes until it is a new moon.
    • ↑ However, a blue moon can also refer to the third full moon in a season with four full moons.↑ Sinnott, Roger W., Donald W. Olson, and Richard Tresch Fienberg (May 1999). "Whats a BlueMoon?". Sky & Telescope. Retrieved 2008-02-09. "The trendy definition of "blue Moon" as thesecond full Moon in a month is a mistake."
    • The moon rises and sets every day, appearing on the horizon just like the sun. The timedepends on the phase of the moon. It rises about 30 to 70 minutes later each day thanthe previous day, so the moon is out during daytime as often is its out at night. At thetime of the new moon, the moon rises at about the same time the sun rises, and it setsat about the same time the sun sets. As the days go by (as it waxes to become acrescent moon, a half moon, and a gibbous moon, on the way to a full moon), the moonrises during daytime (after the sun rises), rising later each day, and it sets atnighttime, setting later and later each night. At the full moon, the times of moonrise andmoonset have advanced so that the moon rises about the same time the sun sets, andthe moon sets at about the same time the sun rises. As the moon wanes (becoming ahalf moon and a crescent moon, on the way to a new moon), the moon rises during thenight, after sunset, rising later each night. It then sets in the daytime, after the sunrises. Eventually, the moon rises so late at night that its actually rising aroundsunrise, and its setting around sunset. Thats when its a new moon once again.
    • Moon PhasesThe Earth and moon are partially lighted at all times, but the moon is not always seen at full phasebecause of the location of the moon with respect to the Sun and Earth. Observers standing on Earthsee different phases of the moon or differing percents of of the lighted side of the moon. There areeight different phases that an observer on Earth would see during one month. They are, listed in orderof appearance, New Moon, New Crescent, First Quarter, New Gibbous, Full Moon, Old Gibbous, LastQuarter, and Old Crescent.
    • The New Moon is observed when the moonis directly in line with the Sun and Earth. The moon isinterfering with the lighted side of the Earth and therefore cannot be seen by an observer on Earthbecause the moons dark side is facing Earth. Occasionallythe moons orbit will intersect the Earthsplane of revolution, which is called a node position and is in a perfect line between theEarth and theSun. When this occurs, a viewer on Earth will observethe Sun slowly disappear because the moonobscures the Sun from view. This unusual occurrence is called a solar eclipse.
    • The Waxing Crescent phase is the second phase. The New Crescent Moon appearsapproximately 2.66 days after the new moon (Alter, pg. 4). During this phase, the moon is stillvery close in line with the sun, there fore, by the time the sky is dark enough to see the moonit is very low in the west.
    • the First Quarter moon is visible this means the moon is directly in line so that the Earth andmoon both are getting the same amount of sunlight. An observer from Earth sees a halfmoon, therefore, the moons side that is facing the Sun is observedon Earth and the other halfof the moon is facing away from the Sun and is unable to be seen from Earth.
    • Waxing gibbous, After the new moon, the sunlit portion is increasing, but less thanhalf, so it is waxing crescent. After the first quarter, the sunlit portion is stillincreasing, but now it is more than half
    • full moon, the earth, moon, and sun are in approximate alignment, just as the newmoon, but the moon is on the opposite side of the earth, so the entire sunlit part of themoon is facing us. The shadowed portion is entirely hidden from view.
    • Waning gibbous, After the full moon (maximum illumination), the light continuallydecreases. So the waning gibbous phase occurs next
    • The Third quarter and First quarter moons (both often called a "halfmoon"), happen when the moon is at a 90 degree angle with respect to the earth andsun. So we are seeing exactly half of the moon illuminated and half in shadow.
    • Waning Crescent following the Third quarter. which wanes until the light iscompletely gone -- a new moon.
    •  I. Write True if the statement is correct if wrong write the correct answer. 1.) -The moon revolves around the Earth in about one month (27 days 6 hours). It rotates around its own axis in the same amount of time. The same side of the moon always faces the Earth; it is in a synchronous rotation with the Earth. 2.) -Moon has no water. 3.) -The moon has 8 phases. 4.) -A blue moon can also refer to the third full moon in a season with four full moons. 5.) -The moon was appearing in the horizon like the sun.

    •  II. Identify the following words 1.) -the earth, moon, and sun are in approximate alignment, just as the new moon, but the moon is on the opposite side of the earth, so the entire sunlit part of the moon is facing us.
