How does the moon affect ocean tides?

How does the moon affect ocean tides?

The moon's gravitational pull is the primary force that causes ocean tides. As the moon orbits Earth, its gravity pulls on the water, creating bulges that we experience as high tides.

What about the sun? Does it have an effect too?

Yes, the sun also affects tides, but to a lesser extent than the moon. When the sun, moon, and Earth align, we experience spring tides, which are higher than normal. Conversely, during the first and third quarters of the moon, we have neap tides, which are lower.

Are there other factors that influence tides?

Absolutely! Other factors include the shape of the coastline, ocean floor topography, and local weather conditions. These can all modify the height and timing of tides.

How often do tides occur?

Tides typically occur twice a day, with two high tides and two low tides in most coastal areas, although this can vary.
