It wont close but any outdoor rides/ roller coasters will close until it's safe to open again.
No it usually kept running
Not really. But we weren't faced with a downpour the day we went. A lot of the rides are indoors (VR, 4D Movies, etc.) so it wouldn't affect those.
Out side rides close when bad whether is one mile out of park
No some rides and outside things may not be available until rain stops
