What Causes Tides?
The daily rise and fall of Earth's waters on its coastlines are called tides. As the tide comes in, the level of the water on the beach rises gradually. When the water reaches its
highest point, it is high tide. Then the tide goes out, flowing back toward the sea. When the water reaches its lowest point, it is low tide. Tides are caused by the interaction
of Earth, the moon, and the sun.
Neap Tides in between spring tides, at the first and third quarters of the moon, the sun and moon pull at right angles to each other. This line-up produces a neap tide, atide
with the least difference between low and high tide. During a neap tide, the sun's gravity pulls some of the water away from the tidal bulge facing the moon. This acts to "aven
out the water level over Earth's surface, reducing the difference between high and low tides.
