at and the Sun is at Answer 1 Selected Answer 2 perigee perihelion 1 1 A tidal pattern with two nearly equal high tides and two nearly equal low tides per lunar day is called a tidal pattern Answer 1 Selected Answer 2 False Question 11 1 out of 1 points 1 1 1 1 Question 12 1 out of 1 points Answer 1 Selected Answer Semidiurnal 2 Question 13 1 out of 1 points 1 1 day is called a tidal pattern 1 A tidal pattern with one high tide and one low tide per lunar Answer 1 Selected Answer 2 Diurnal States 1 1 What tidal pattern occurs along the West Coast of the United Answer 1 Selected Answer 2 Mixed 1 1 Under ideal conditions for the West Coast of the United States the time interval between a high tide and the very next high tide would be Answer 1 Selected Answer 2 12 hours 25 minutes 1 1 1 1 1 Question 14 1 out of 1 points Question 15 1 out of 1 points Question 16 1 out of 1 points 1 1 1 What would tides be like on Earth if the Moon did not exist Answer 1 1 Selected Answer 2 Tides would occur but the tidal range would be reduced patterns 1 1 In the open ocean tidal currents follow which of the following Answer 1 Selected Answer 2 Rotary the tides is called 1 1 Water that is flowing out of a bay as a result of a change in Answer 1 Selected Answer an ebb current 2 Question 17 1 out of 1 points Question 18 1 out of 1 points 1 1 1 1 1 1 Question 19 1 out of 1 points 1 1 What is a tidal bore Answer 1 Selected Answer 2 a true tidal wave caused by an incoming high tide that moves up certain rivers 1 1 1 1 Question 20 1 out of 1 points FALSE 1 1 Which of the following statements about tidal power plants is Answer 1 Selected Answer 2 There are no existing tidal power plants anywhere in the world Understanding the Concepts Question 1 1 out of 1 points 1 1 Select the best ending to the following statement The tides are considered an example of shallow water waves because the tidal bulges have a wavelength that is on the order of Answer 1 Selected Answer 2 thousands of kilometers Question 2 3 out of 3 points 1 1 1 1 Of the following statements about the force of gravity be Answer tween two bodies which is are true 1 Selected Answers 2 The force of gravity between two bodies increases with an increase in mass The force of gravity between two bodies decreases as dis tance increases The force of gravity between two bodies is most affected by a change in distance 3 4 Question 3 3 out of 3 points 1 1 which is are true 1 1 Of the following statements about forces and tidal bulges Answer 1 Selected Answers 2 On the side of Earth closest to the Moon a tidal bulge will form as a result of an excess of gravitational force Tidal bulges are produced on both sides of Earth from the Moon and the Sun On the side of Earth facing away from the Sun a tidal bulge will form due to an excess of centripetal force 4 3 Question 4 4 out of 4 points 1 1 1 1 Of the following statements about the tides which is are Answer true 1 Selected Answers 2 There are two tidal bulges on Earth caused by the Moon one facing the Moon and the other facing away from the Moon 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 Both Earth and the Moon orbit around their common cen ter of mass called the barycenter The tides are caused by an imbalance between the cen tripetal force and the gravitational force of the Moon and the Sun 3 4 5 Question 5 2 out of 2 points 1 1 barycenter of the Earth Moon system which is are true 1 1 Of the following statements about the location of the Answer 1 Selected Answers 2 It is located at a point beneath Earth s surface within the mantle It is located at the center of mass of the Earth Moon sys tem 3 Question 6 3 out of 3 points 1 1 1 1 Of the following statements about the contribution of the Sun Answer and the Moon to Earth s tides which is are true 1 Selected Answers 2 The lunar tidal bulges are about twice the size of the solar tidal bulges The Sun s contribution to the tides is less than that of the Moon The Moon exerts over twice the gravitational pull of the Sun on Earth …
