What causes tides in the ocean?

Transcript

Tides in the ocean are primarily caused by the gravitational pull of the moon, which generates tidal bulges on Earth, leading to high and low tides approximately every 12 hours and 25 minutes as Earth rotates.The sun also affects tides, but its influence is weaker due to its greater distance from Earth.The tidal force of the moon is about twice as strong as that of the sun, making it the dominant force in creating tides.

Tidal Bulge
Tides in the ocean are primarily caused by the gravitational pull of the moon, which generates tidal bulges on Earth, leading to high and low tides approximately every 12 hours and 25 minutes as Earth rotates[1][3][4].

Illustration showing how the gravitational force of the Sun and Moon act together and create spring tides at New Moon and Full Moon.
The sun also affects tides, but its influence is weaker due to its greater distance from Earth[2][6].

The tidal range is smallest at the 2 Quarter Moons.
The tidal force of the moon is about twice as strong as that of the sun, making it the dominant force in creating tides[2].
