Question

Even though the Moon is much smaller than the Earth, it still exerts a pull of gravity on our planet. Explain what effect the Moon’s pull has on the Earth, and why this occurs.

Answer 1

The moon's pull causes high and low tides on earth

Answer 2

The above answer is correct - the effect of the moon is to cause tides, although the sun has influence too - if the two are aligned they cause a particularly high tide known as a "spring tide", just like water welling up to the surface of the land is known as a "spring".
