The correct answer is 1,2,3. Key Points Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. The Moon's pull is the major cause of a tide. Hence statement 2 is correct. Sun's gravitational pull and centrifugal force due to the gravitational pull of the earth to a lesser extent so caused types. Hence statements 1and 3 are correct. The tide-generating force is the difference between the gravitational attraction of the Moon and the centrifugal force. The movement of water is caused by Meteorological effects like winds and atmospheric pressure change and is known as surges. An object traveling in a circle behaves as if it is experiencing an outward force. This force is known as centrifugal force. Water on sea experiences this force due to the rotation of the earth. The moon and the sun’s gravity try to pull at anything on the Earth to bring it closer. Tides also occur in large lakes, the atmosphere, and within the solid crust of the earth, acted upon by these same gravitational forces of the moon and sun.
