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 are the rotation of the Earth.
Statement IIThe Earth rotates from west to east.
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 the rise and fall of sea level caused by the gravitational pull of the Moon and the Sun combined with the rotation of the Earth, so Statement I is true. The Earth rotates from west to east, so Statement II is true. But the west-to-east rotation only sets the timing of the tides; the rise and fall itself is caused by the gravitational differential, so Statement II is not the correct explanation of Statement I.
