which/from which/in which/where

[lovecherry]

hi,
Would you pls teach me how to you which/from which/ in which/where? Because i usually misuse those words.
I would like to give you an example as following:
The shifting sands have led to a significant increase in sandstorms, the grit from which can travel as far as the western United States.

Would you pls explain why from which is used in that sentence?
Would you pls tell me what is difference between sand storms and sandstorms?

thanks and best regards!

Good morning.

(1) I think that maybe (maybe) the term first started as "sand storm." But many terms in English soon become one word: sandstorm.

(2) I think in old English, we could use "whence," but today most people prefer to use "from which."

(a) In your sentence, "which" refers to "sandstorms." So: the grit from sandstorms can travel as far as the western United States.

(3) Your sentence is considered as very elegant English. I think you could also write: The shifting sands have led to a significant increase in sandstorms, which contain grit that can travel as far as. ...

(i) As you can see, "which" (the relative pronoun) refers to "sandstorms."

Thank you.
