The roche limit of a planet is where the moon's gravity keeping it together
Is weaker than the planet's gravity, tearing the moon apart.
Here, the grey circle is the roche limit. the red moon is quickly destroied as
its in the roche limit. The yellow moon acumulates mass and soon follows the
same faith as the red moon. The green and blue moon are not teared apart because they are not in the roche limit.

You have the explanation about right, but it isnt that the moon's gravity needs to be less than the planet's gravity, it's that the difference in gravitational magnitude imparted by the planet between the nearest and furthest points of the small body must be greater than the difference in gravitational magnitude imparted by the moon holding those same points together.

Some comments just give me a headache -_-
I wanted this to be simple so others which are new to the subject can understand.

What UnityDogGaming04 meant is "when the difference of the planet's gravity between the closest point of the moon and the farthest point of the moon exceeds the gravity that holds the moon together"

A good indicator of whether an object will break apart past a certain distance is to compare its physical size to its sphere of influence, the roughly spherical region surrounding it such that any object within this bubble is most strongly effected by the object, and not as strongly by other objects surrounding it

Aftermath of the planet: It has a beautiful ring now:)
