it takes the earth twenty-four hours to travel around its axis once.we look at the sun and say it rises and travels across the sky,but the sun doesn't really do so.it is the turning of the earth that makes us feel as if the sun were moving across the sky.we can't see earth is moving because everything else on the earth twenty-four hors,first one earth is facing the sun,we can say it is day.when our half is away from the sun,we say it is night.it is the turning of the earth that tells us when to go to bed and when to get up.
