> **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.** Earth rotates once during a 24-hour period. It rotates 180 degrees in 12 hours. The moon rotates around the earth in 12 hours.The moon's gravitational force pulls on water in the oceans so that there are bulges in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon. The bulge on the side of the Earth opposite the moon is caused by the moon pulling away from the water on that side. If you are on the coast, you will have a high tide. The areas of the earth where the bulging occurs will have high tide, and the other areas will have a low tide. The pair of bulges is the Earth’s twin high tides, and they stay constantly aligned with the Moon. It is the Earth and ocean rotating beneath them that causes the ocean to rise and fall twice a day in any given place.
 * 1) View the top diagram above. **Compare the relative positions of the earth, moon and sun to explain the differences between new moon, half moon and full moon phases. In the new moon phase, the moon is in between the sun and earth, and the are in a line. The entire front side of the moon is dark and the back side is all lite. In the full moon phase, the moon, sun and earth are all in a line, but the moon is on the opposite side of the earth. The side of the moon we see, is fully lite. In the half moon phase, the moon is in a 90 degree angle to the sun and the earth. So half of the moon is lite and the other half is dark.**
 * 2) View the example of the tide chart for the Gandy Bridge for a day. 2015 Tide Chart for Gandy Bridge
 * 1)  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. //(Note:// On the Tide Tables there are tidal coefficients which tell us the amplitude of the tide forecast //(difference in height between the consecutive high tides and low tides in any given area). The highest possible tidal coefficient is 118, corresponding to the greatest high or low tide there can be, excluding meteorological effects. Tidal coefficients are calculated from the following parameters or from the sun and the moon: straight ascension, declination, parallax and the distance between the Earth and the celestial body.)//
 * 2) //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.**//
 * 3) 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**. The highest coefficient of tides will occur on October 27. On October 27, there will be a full moon and the earth, sun and moon are all in a line. The high tides will occur at 2:36 a.m. ad 4:19 p.m. The low tides will occur at 9:36 a.m. and 9:15 p.m. The lowest coefficient occurred on October 5. There was a third quarter (half) moon ad the earth, moon, and sun were in a 90 degree angle from each other. The low tides occurred at 2:16 a.m. and 4:53 p.m. Only one high tide and it was at 8:33 a.m. It appears that when there is a full moon, there are high tides and high coefficients, and when there is a half moon, the tides are lower and the coefficients are lower. When there is a low coefficient, the low tide will occur the earliest in the morning, and when there is a high coefficient the high tide will occur earliest in the morning. It also appears that when the moon, sun and earth are in a line, the tides are the highest.

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.
 * 1) The earth is a crescent phase in the first picture because I would see a little bit what is light and the moon will be in waxing gibbous.
 * 2) In the second picture of the earth is quarter earth phase because half of the moon shows half of the earth that's dark.
 * 3) It's a gibbous earth and the moon will be a waxing crescent.
