Question

1. base your answer to the following question on the graph below, which shows two days of tidal data from a coastal location in the northeastern united states. tidal changes the change in the tides as shown on the graph is primarily the result of (1) the moons rotation and revolution (2) earths rotation and revolution (3) the moons rotation and earths revolution (4) earths rotation and the moons revolution 9) base your answer to the following question on the passage below and on your knowledge of earth science. supermoon eclipse on september 27, 2015, a rare total lunar eclipse of a supermoon occurred. a supermoon occurs when the entire lighted half of the moon faces earth (full moon phase) and the moon is at its closest point to earth in its orbit. at this time, the moon will appear 14% larger and 30% brighter than normal. supermoon events are rare, but a total lunar eclipse during a supermoon is even more rare. there have been only six total supermoon lunar eclipses since 1900. the next one will not happen until 2033. the time it took for the moon to go from this supermoon to the next full moon phase was (1) 27.3 days (2) 365 days (3) 15 days (4) 29.5 days

Explanation:

• For question 8: Tides are mainly caused by the gravitational pull of the Moon. Earth's rotation causes the daily cycle of tides, and the Moon's revolution (orbiting Earth) affects the tidal pattern over time.
• For question 9: The synodic month (time between successive full - moons) is approximately 29.5 days. A supermoon is a full - moon when the Moon is at its closest to Earth. The time from one full - moon (supermoon in this case) to the next full - moon is based on the synodic month.

Answer:

1. (4) Earth's rotation and the Moon's revolution
2. (4) 29.5 days
