Why moon gravity affected sea tides on earth?
[c=359E00]isn't that moon's gravity weaker than earth's gravity?[/c]

Gravity is an attractive force, so two massive objects orbiting one another will bend and warp each other. This distortion is more pronounced in liquids and is also transferred from the distortion of the earth's crust which produces tides.
The earth being more massive does have more gravity but that doesn't discount the moon's gravity. The moon still has a large amount of it's own.
In turn the gravity of the earth also distorts the shape of the moon as well. But since it doesn't have liquid on it's surface there are no tides to speak of. But there are moonquakes.
