 * Questions and Answers: **


 * 1. Compare the relative positions of the earth, moon and sun to explain the differences between new moon, half moon and full moon phases. **
 * The new moon occurs when the moon is positioned between the earth and sun. First quarter and third quarter moons (known as the half moon) happens when the moon is at a 90 degree angle with respect to the earth and sun. So we are seeing exactly half of the moon illuminated and half in shadow. During the full moon, the earth, moon, and the 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. The shadowed portion is entirely hidden from view.


 * 2. View the example of the tide chart for the Gandy Bridge for a day. 2015 Tide Chart for Gandy Bridge Using the positions of the moon relative to a location on earth, explain why the tides alternate from low to high during a 24 hour period and why there are usually 2 high tides alternating with low tides each day. **
 * The tides on earth alternate from high to low because the moon has a strong gravitational pull so when the earth rotates the water is pulled in and out depending on the location of the moon compared to the oceans. we have two high tides and two low tides because the water is pulled more, then pulled less, them pulled more, than pulled less by the moons gravitational pull in one 24 hour time span.


 * 3. Use the data from Gandy Bridge TidesTampa Bay Tides to create a spreadsheet in Open Office with the coefficient of the tides for the days in the month of October, 2015. Then create a line graph of the data. Indicate that the first row and first columns are labels. Be sure to label the X and Y axis, and to provide a title. Be sure to include units. **


 * 4. Save the Tide Height spreadsheet as 8 last name initial tide. Save it as an html document. Saving it as an html will convert the chart to a jpeg. Copy the spreadsheet data and paste it on your TideMoon page. Then Upload the jpeg of the chart to your page. **


 * 5. View the Moon Phases October 2015 on the same Gandy Bridge Tides . Find the moon phases for the high coefficients and low coefficients on the graph. Provide an explanation for the pattern of high coefficient of tides alternating with the low coefficient of tides during the month based on the relative position of the earth, moon and sun. **
 * If the sun and the moon are aligned with the earth in the middle than the high tides and the low tides will be higher but if they are closer together they will cancel each others gravity out.


 * 6. View the 3 images below. Explain for each image, the relative position of the sun, moon and earth that would result in the phase of the earth as seen in each of the photos. For each picture indicate what the corresponding phase of the moon would be when viewed from earth on the same day each of the photos of the earth was taken. **


 * For the first image of the moon's view of the Earth is shown in a crescent phase from the moon, waxing or waning gibbous.
 * For the second image which shows the first quarter Earth from the moon, is only possible if the moon is in the first/third quarter.
 * For the last image which shows the waning or waxing gibbous earth from the moon, the moon must be in a waxing/waning crescent to see the Earth in this way.
