Best practice
When using "which impacts", ensure the clause it introduces provides essential information rather than just additional details. If it's non-essential, consider using "which affects" or rephrasing for clarity.
Common error
Avoid using "that" instead of "which" when introducing a non-restrictive clause (a clause that adds extra information but isn't essential to the sentence's meaning). "Which impacts" is correct in such cases, while "that impacts" would be suitable for restrictive clauses.
