How do I form a sentence pattern for:
The more/less X happens, the more/less Y happens
E.g. The more you stir, the faster the salt dissolves.
The colder the weather, the more time it takes for snow to melt.
EDITED to include formation and examples
There are also several other grammar patterns that express "as one thing changes (grows/increases/decreases/etc.) another thing changes with it" (the key is that both things are changing).
These used to be JLPT ２級 patterns, but since they changed it to the new N1-N5 system, I don't know which level they are anymore.
Anyone who took formal courses on Japanese would have learned this pattern: X-eba X hodo Y.
