ANSWER:
The gravitational influence of the moon cause tides to occur.
EXPLANATION:
- Tides are caused by the 'gravitational pull' due to Sun and Moon on earth. The gravitational pull is the 'force of attraction' between two huge masses.
- So, there is a pull force between the 'moon and the Earth' due to which the waters in the ocean cause tides, the same is for the sun and earth.
- Though sun has also influence in causing tide but moon being much nearer has the highest influence for the tides to occur in the oceans.
