Tidal waves on earth are caused by Moon's Gravity 😲🤯. The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur. In simple, The moon's gravity creates tidal bulges on both the near and far sides of Earth, causing high tides as different parts of Earth rotate through them. 🎥 :
