Statement ITides 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.
Statement IIEarth rotates from the West towards the East once in 24 hours with respect to the Sun.
General KnowledgeGeography
- ABoth the statements are individually true and Statement II is the correct explanation of Statement I.
- BBoth the statements are individually true, but Statement II is not the correct explanation of Statement I.
- CStatement I is true, but Statement II is false.
- DStatement I is false, but Statement II is true.
Explanation
Tides are caused by the combined gravitational pull of the Moon and the Sun together with Earth's rotation — Statement I is true. Earth does rotate from west to east once in about 24 hours with respect to the Sun — Statement II is true. But Statement II is merely a fact about rotation; it does not explain the tidal mechanism, which depends on differential gravitational forces. Both statements are true, but II is not the explanation of I — option B.
