Period (Do not put nd, rd, or th after the number!) *
Which physical law best describes the reason that ocean tides occur? *
Which phase of the moon can result in exceptionally high tides and exceptionally low tides? *
Exceptionally high high tides and exceptionally low low tides are called *
The greatest tidal pull (highest high and lowest low tides) occurs when *
The Sun's tide making force is about ___________ of the Moon's tide making force. This is primarily due to the fact that the Moon is _______________ to Earth. *
What part of North America would have the greatest tidal range? *
Tidal range is the difference between the highest high and lowest low tides seen in a given area during a particular phase of the Moon.
What condition would create the greatest tides encountered throughout the whole year? *
Apogee is when the Moon is farthest from Earth. Perigee is when the Moon is closest to Earth. Aphelion is when the Earth is farthest from the Sun. Perihelion is when the Earth is closest to the Sun.
Explain why it is possible to have two tidal ocean bulges on opposite sides of the Earth when the Moon can only be on one side of the Earth at any given time? *
Hint: Think about what happens when you accelerate away from a stop light in a car like a Porsche with great acceleration. What happens to your body in the seat? Do you move backwards as the car accelerates forwards? Does the Earth accelerate toward the pull of the Moon and the Sun? If so, what will happen to the ocean water on the side of the world facing away from the Moon? In physics, we call this inertia, the tendency of an object at rest to stay at rest.
Look at the website called "How do Tides Work?" This site is found by clicking on the link at the top of this homework in the title. Approximately how many hours fall in between high and low tide and Cape Porpoise Harbor, Maine? *
What is the reason for the difference in time between high and low tide in the last question? *
