1.The moon generates a tidal bulge that is about twice the magnitude of that generated by the sun.A) TrueB) False2.Waves refract and change direction when they approach a beach because the part of the wave in shallow water ___________ relative to the wave segment in deep water.A) slows downB) speeds upC) moves at the same speedD) reverses direction3.A mesotidal coast with a diurnal tide would have:A) a low tide every 12 hrs. 25 min. with less than 2 m amplitudeB) a low tide every 24 hrs 50 min. with 2 to 4 m amplitudeC) a low tide every 12 hrs. 25 min. with greater than 4 m amplitudeD) a low tide every 2 days greater than 40 m amplitudeE) a low tide every 12hrs 25 mins. with 2 to 4 m amplitude4.Groins tend to cause erosion on their upstream side (the side from which longshore currents originate) because they block the longshore current.A) TrueB) False5.Tides are a product ofA) gravity and wind.B) surface water currents driven by wind.C) Ekman transport and thermal transport.D) gravitational and centrifugal forces.E) all of the above.6.During storms:A) sand accumulates on the beachB) sand accumulates in offshore barsC) the beach tends to erode and become flatterD) the beach tends to build up and become steeperE) B and C7.Tides do not vary from summer to winter in a given location because Earth is always the same distance from the sun and moon.A) TrueB) False8.For Semi-diurnal tidesA) there is a high tide about twice a day with a period of 12 hrs. 25 mins.B) there is a low tide every 2.73 days.C) there is a high tide about once a day with a period of about 24 hours.D) high tides cannot be predicted by the dynamic theory of tides.E) none of the above9.The tidal bulges on Earth:A) rotate 360° during a day just like everything on Earth’s surfaceB) make half a revolution each day, which is why there are two bulges.C) remain fixed in place with respect to the moon while the Earth rotates under them.D) are always directly over the equator.E) all of the above10.Longshore currents are generated byA) variable offshore windsB) short-crested wavesC) waves coming in at an angle to the coast and breaking before they are parallel to the coastD) groins and jettiesE) All of the above11.Amphidromic points are:A) semi-diurnal tidesB) the center of the circus "big top"C) the point around which tidal waves rotate, as described by cotidal and corange linesD) the moment of change from spring to neap tideE) all of the above
I need those answer By 4/12 noon around 12.
Those questions due to 4/20 Thanks.
Oceanic crust provides a detailed record of the changesin Earth's magnetic field for the past 3.8 billion years
The Red Sea is an example of
A) a transform fault exposed on land
B) a subduction zone and plate collision
C) a rift system creating new oceanic crust
D) a volcanic arc
The three types of plate boundaries are
A) Convergent, Conservative, Transitional
B) Divergent, Transform, Convergent
C) Passive, Aggressive, Republican
D) Transitional, Transform, Conservative
Ocean depth increases with distance from spreading ridges.
The boundary between the Pacific plate and the Nazca plate is a subduction zone.
The Hawaiian island chain and the Emperor Seamounts indicate that the Pacific plate is stationary
The forces that cause plate tectonic motions are most likely
A) slab pull and ridge push
B) transform faults and black-smokers
C) mantle drag and deep-ocean currents
D) passive margin subsidence
Passive continental margins have
A) stable, wide continental shelves
B) narrower continental shelves than active margins
C) volcanic activity at their edges or just off shore
D) earthquakes associated with transform faults
E) none of the above
The creation of new seafloor at subduction zones is balanced by destruction of material at transform faults.
The San Andreas fault in California is an example of

It is a PPT but i can not upload.
But i can give you a link you can download it.
Hi Judy the answer was fine. And you should tell me which chapters i should give you. I can add 10 more for bonus. Thanks.
Hi Judy They dont upload chapter3 and 4. But they will on next monday. I will give you that 3 and 4 on monday. Thank you so much.
