Explanation:

• Explanation: Both statements are correct Supplementary notes: Tidal Bulge The study of tides is very complex, spatially and temporally, as it has great variations in frequency, magnitude and height.
• Tides are caused due to gravitational attraction of sun and moon, and centrifugal force due to rotation of earth.
• The moon’s gravitational pull to a great extent and to a lesser extent the sun’s gravitational pull, are the major causes for the occurrence of tides.
• Another factor is centrifugal force, which is the force that acts to counter balance the gravity.
• Together, the gravitational pull and the centrifugal force are responsible for creating the two major tidal bulges on the earth.
• The ‘tide-generating’ force is the difference between these two forces; i.
• e.
• the gravitational attraction of the moon and the centrifugal force.
• On the surface of the earth, nearest the moon, pull or the attractive force of the moon is greater than the centrifugal force, and so there is a net force causing a bulge towards the moon.
• On the opposite side of the earth, the attractive force is less, as it is farther away from the moon, the centrifugal force is dominant.
• Hence, there is a net force away from the moon.
• It creates the second bulge away from the moon.
• On the surface of the earth, the horizontal tide generating forces are more important than the vertical forces in generating the tidal bulges.
• The tidal bulges on wide continental shelves have greater height while lower at narrower shelves.
• When tidal bulges hit the midoceanic islands they become low.
•    The shape of bays and estuaries along a coastline can also magnify the intensity of tides.
• Funnel-shaped bays greatly change tidal magnitudes.
• When the tide is channeled between islands or into bays and estuaries they are called tidal currents.
