Chapter 9 Homework The tide generating force is inversely proportional to the cube of the distance True True There is no horizontal tide generating force on Earth at points directly below and opposite the Moon The barycenter follows a smooth orbit around the Sun The difference between centripetal forces and gravitational forces is called the resultant force If the resultant force has a significant horizontal component tangential to Earth s surface it produces tidal bulges on Earth creating what are known as tide generating forces A lunar day is 24 hours and 50 minutes in duration Measurable tidal bulges occur in the ocean the atmosphere and Earth s crust Of the following statements about the force of gravity between two bodies which is are true The force of gravity between two bodies decreases as distance increases The force of gravity between two bodies increases with an increase in mass The force of gravity between two bodies is most affected by a change in distance Of the following statements about the tides which is are true Both Earth and the Moon orbit around their common center of mass called the barycenter There are two tidal bulges on Earth caused by the Moon one facing the Moon and the other facing away from the Moon The tides are caused by an imbalance between the centripetal force and the gravitational force of the Moon and the Sun Although we observe the tides coming in and going out in reality Earth is rotating into and out of various tidal bulges which produces changing tides Of the following statements about the contribution of the Sun and the Moon to Earth s tides which is are true The Moon exerts over twice the gravitational pull of the Sun on Earth s tides because of its proximity to Earth The Sun s contribution to the tides is less than that of the The lunar tidal bulges are about twice the size of the solar tidal The most important factor that causes ocean tides on Earth is the If the side of Earth that faces the Moon experiences a tidal bulge high tide then the opposite side of Earth will experience a Moon bulges Moon tidal bulge or high tide A lunar day is in duration 24 hours and 50 minutes It is Thursday and an angler is planning a fishing trip in two days on Saturday The angler knows from experience that the fishing is best at a particular location at the beginning of high tide He does not have a tide table but the angler noted that the high tide on Thursday was at 12 15 PM At what time on Saturday should he plan to arrive to start fishing assuming that this location has a diurnal tide type The low and high tides experienced on Earth are the result of 1 55 PM tidal bulges greater than nadir exceed two The Moon s influence on Earth s tides is the influence of the Sun The weakest gravitational force caused by the Moon is called the which is found at the point on Earth farthest from the Moon On the side of Earth closest to the Moon gravitational forces the centripetal forces Resultant forces result in tidal bulge s on Earth What common household item is used in this video to demonstrate the forces that act on bodies to create tides on Earth a racquetball A centrifugal force is one that is directed and a centripetal force is one that is directed outward inward What path did the rotating item take at the moment when the string was let go It traveled in a straight line path that was tangent to its circular orbit Tides occur on Earth because of an imbalance between gravity and centripetal force If it is January and the Moon is in syzygy what additional factor would contribute to extreme tidal ranges around the world the Moon in perigee A spring tide occurs once per month Syzygy produces maximum tides once every 1 600 years if the relative positions of the Sun to the Earth and the Moon to the Earth are just right The plane through the ellipse that marks the revolution of the Earth around the Sun is called the ecliptic The vertical difference between consecutive high and low tides is called the False True True tidal range Spring tide occurs about twice per month Neap tides occur when the moon is in quadrature When the Earth is at its greatest distance from the sun it is said to be at aphelion Examine the five words and or phrases and determine the relationship among the majority of words phrases Please identify the word and or phrase that does NOT fit the pattern Enter only the letter of the answer caps no period and not the full entry in the field below B Nadir A proxigean tide occurs when the Moon is at perigee at a time of syzygy Of the following statements about lunar phases which is are true Over the few days of a waxing crescent moon the tidal range decreases Over the few days of a waxing gibbous moon the tidal range Increases What do we call the tide that occurs when constructive interference between lunar and solar bulges produces a large tidal range spring tide What are tides the regular daily rises and falls in sea level caused by the gravitational attraction of the Moon and Sun on Earth Why are high tides found simultaneously on opposite sides of Earth The tidal bulges occur on both sides of Earth that are aligned with the tide generating body Why does the Moon generate larger tidal forces than the Sun Although the Sun is bigger the Moon is much closer What do we call the tide that occurs when destructive interference between lunar and solar bulges produces a small tidal range neap tide How many spring and neap tides will a tide recording station experience in a given month 2 spring tides and 2 neap tides The center of an open ocean tidal system is called a an amphidromic point What tidal pattern would best describe a coastline that experienced a maximum tidal range of 6 ft in the morning and a smaller 2 ft range in the late afternoon A tidal pattern with one high tide and one low tide each lunar day is called a semidiurnal tidal pattern mixed false A diurnal tidal pattern is common along the Pacific coast of the United States false An area that experiences diurnal tides will have one high tide and one low tide daily In the United States semidiurnal tides commonly occur along the Atlantic coast Examine the five words and or phrases and determine the relationship among the majority of words phrases Please identify the word and or phrase that does NOT fit the pattern Enter only the letter of the answer caps no period and not the full entry in the field below D quadrature Some of the tide height numbers in your tide table are preceded by minus signs or
