Both the statements are individually true, but Statement II is not the correct explanation of Statement I. The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide. Change in position of the sun and moon in relation to the earth is one of the factors that influences tide (revolution). Earth rotates or spins towards the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.
