![]() The gravitational attraction of the Sun also plays a small role in the formation of tides. Elsewhere on the Earth, the ocean recedes, producing low tides. The rotational force causes water to pile up as the water tries to resist that force, so high tides form on this side, too. On the side facing away from the Moon, the rotational force of the Earth is stronger than the Moon’s gravitational pull. The side of the Earth closest to the Moon experiences the Moon’s pull the strongest, and this causes the seas to rise, creating high tides. The moon’s gravitational pull on the Earth and the Earth’s rotational force are the two main factors that cause high and low tides. It often accompanies a new moon and when the moon is closest to the Earth. A high tide that is significantly higher than normal is called a king tide. Some freshwater rivers and lakes can have tides, too. ![]() Low tide is when it recedes to its furthest extent. High tide is when water advances to its furthest extent onto the shoreline. The alternating advance and retreat of seawater along a coastline is called a tide.
