Q 37CASE BASED QUESTIONS(4 Mark)4 Marks
Read the passage given below and answer the following questions.
The rhythmic rise and fall of ocean water twice in a day is called a tide. It is high tide when water covers much of the shore by rising to its highest level. It is low tide when water falls to its lowest level and recedes from the shore. The strong gravitational pull exerted by the Sun and the Moon on the Earth's surface causes the tides. The water of the Earth closer to the Moon gets pulled under the influence of the Moon's gravitational force and causes high tide. During the full moon and new moon days, the Sun, the Moon and the Earth are in the same line and the tides are highest. These tides are called spring tides. But when the Moon is in its first and last quarter, the ocean waters get drawn in diagonally opposite directions by the gravitational pull of Sun and Moon resulting in low tides.
(i) What causes the rhythmic rise and fall of ocean water, known as tides?
(a) Winds scraping across the ocean surface
(b) Earth's rotation on its axis
(c) Gravitational pull of the Sun and the Moon
(d) Underwater volcanic eruptions
(ii) What characterises neap tides?
(a) High tides with maximum water coverage
(b) Low tides with minimal water coverage
(c) Tides occurring during the first and last quarter of the Moon
(d) Tides caused by volcanic eruptions
(iii) Spring tides occur during which of the following?
(a) Half Moon $\quad$ (b) Full Moon $\quad$ (c) Quarter Moon $\quad$ (d) None of these
(iv) How tides are helpful to us?
(a) They help in navigation
(b) They help in fishing
(c) They help to raise their water level close to shores
(d) All of the above
