I think rift means a break or something, but I am not entirely sure.
For ridge, I have no idea.

A rift occurs where two tectonic plates are pulling apart, in a rift new crust is not formed, the East African rift is an example. Imagine a rift like a stick of taffy being pulled. A ridge is where two plates are moving apart but new crust is being formed. The crust thins so much from the plates moving apart that magma breaks through and hardens forming new crust. The new crust developes into a ridge, and it looks like a mountain chain. While they seem like they are the same thing they are different features. If rifting continues long enough a ridge might develope but that does not always happen. Example: there is evidence that the mississippi river valley follows an old rift valley. So just because a rift occurs that does not mean it will become a ridge. Hope that clears things up for you.

A ridge is created at a rift. Think about a Mid-ocean ridge. The plates are diverging and molten rock is rising through the rift building up and creating a ridge.

If you think about what the word ridge means, you'll get the meaning in geology.
And rift means break, just as you thought.
Most geological words that sound like ordinary words are just ordinary words used in a geological context.
What that word means in ordinary English is pretty close to what it means in geology (they didn't make up a whole new language using English words but giving them different meanings).

Well, I have been known in the past to ask for just a tad more of Kahlua in my coffee, so a tad could be a jigger. Or, tad could be short for tadpole (meaning the same as the little kid). It has been a tad cold here this past week and a lot rainy.
