why are there two high tides a day about 12 hours apart from each other? earth revolves around the sun once during that time. earth rotates entirely on its axis once during that time. the moon revolves around earth once during that time. the moons orbit is in line with earths orbit twice a day.
Answer
Brief Explanations:
Tides are caused by the gravitational pull of the moon on Earth's oceans. As Earth rotates on its axis, different parts of the planet face the moon at different times. There are two high - tides a day because Earth rotates once on its axis in about 24 hours, and as it rotates, a location on Earth passes through two tidal bulges (one when facing the moon and one when on the opposite side due to inertia) approximately 12 hours apart.
Answer:
Earth rotates entirely on its axis once during that time.
