How the Moon Affects the Tides
The term tides refers to the rising and falling of sea level with respect to land. Have you ever thought about what causes this movement of the ocean though? The answer is the gravitational pulls of the moon, sun and Earth. Due to the fact that the moon is much closer to the Earth than the sun, its gravitational pull is stronger. In today's blog, Big Bags USA® discusses how the moon affects the tides and what that means in terms of flood risk. Lunar Tides While the moon's gravitational pull isn't strong enough to move anything on land, the same doesn't go for water. As the Earth rotates, the distance between the Earth and the moon in any particular given spot changes. That change in distance affects the amount of gravitational pull the moon has on that particular area. The moon's pull is strongest at whichever spot of Earth is closest to it, and this causes the water to bulge toward the moon. These areas where bulging occurs experience high tide, while the ...
