Question

How are tides caused by the gravitational pull of the moon and sun?

Answer 1

Gravity is one major force that creates tides. Our sun is 27 million times larger than our moon. Based on its mass, the sun’s gravitational attraction to the Earth is more than 177 times greater than that of the moon to the Earth.

Answer 2

Explanation:  

High and low tides are caused by the Moon.

The Moon's gravitational pull induces something called the tidal force.

The tidal force causes Earth—and its water—to bulge out on its nearest and furthest sides from the Moon.

The Moon is responsible for high and low tides.
