What is the moon’s main effect on Earth?
A Causing earthquakes
B Creating tides in oceans
C Causing insomnia
The most noticeable effect of the moon’s gravitational pull is the tides in Earth’s oceans. The moon’s gravitational force causes the water in the oceans to bulge toward the side facing the moon and the side opposite it. These are known as high tides. The areas between these bulges experience low tides. The sun also contributes to tides, but due to its greater distance, the moon has a stronger influence.
The correct answer is Creating tides in oceans.
