Question

Where does the pattern of the tides come from?

Answer 1

The moon has some gravitational pull on the earth so it causes the water on earths surface to change causing tides

Answer 2

The pattern of the Earth's ocean tides is the result of the interaction of:

-- the changing strength and direction of the force of gravity toward the sun due to its changing position and distance,

-- the changing strength and direction of the force of gravity toward the moon due to its changing position and distance,

-- the rotation of the Earth,

-- the shapes of the coastal boundaries between the Earth's land masses and its oceans.
