Trivia: What is the primary cause of the Earth’s tides?
The moon’s gravitational pull
Earthquakes
Hydrothermal vents
Fluctuating air temperature
Correct Answer: The moon’s gravitational pull
So why is this answer correct? : While the sun also influences tidal movements, the moon has a greater impact because it is much closer to the Earth. As the moon orbits the Earth, its gravity pulls the Earth towards it, including the water in oceans and lakes. The displacement of this water causes high tides and low tides around the Earth during certain times of the day.
