The relationship between the masses of the Earth, moon and sun and their distances to each other play critical roles in affecting tides. Click the image for a larger view. Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the ...


The moon's GRAVITY pulls Earth's water away from Earth Gravity attracts things, if an object has more mass, there will be more gravity. When the moon revolves around the Earth its gravity is just strong enough to pull the tides in the direction that is facing the moon. Since the moon still orbits around the Earth, different faces have different tides, so there are high tides and low tides.


Because ocean tides are the effect of ocean water responding to a gravitational gradient, the moon plays a larger role in creating tides than does the sun. But the sun's gravitational gradient across the earth is significant and it does contribute to tides as well.


An illustration of the moon causing Earth's ocean tides. Shutterstock. When teachers explain ocean tides, they frequently describe how the moon's gravity pulls on Earth and all of its water.


What Causes the Tides? By Lauren Cox, Live Science Contributor | August 5, 2010 08:56am ET MORE; Tides may seem simple on the surface, but the ins and outs of tides confounded great scientific ...


How can the moon cause tides when it does not have gravity strong enough to create it's own atmosphere.In this case how can its gravitational pull cause tides on earth,which at distance from the moon.


Does anything else affect tides? The sun causes tides just like the moon does, although they are somewhat smaller. When the earth, moon, and sun line up—which happens at times of full moon or new moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.


Ocean’s tides are explained in this video: How the tides work? Why the oceans experience two high tides and two low tides each day? The oceans on the earth's surface are attracted to the moon ...


Tides and Water Levels Gravity, Inertia, and the Two Bulges Two tidal bulges are created on opposite sides of the Earth due to the moon's gravitational force and inertias counterbalance.
