Using the propositions "above" and "over"

[Eldar]

Dear teachers,I have a little difficulty using the propositions "above" and "over".
Please look at these sentences:
1)The sky/ clouds is above me. 2)The sun is over me.3)My plane was flying over the city of London.
Are these sentences grammatically correct? Can I use in the first sentence "over" in place of "above"? Please, explain to me what the difference is.
Thank you in advance. God bless you and yours.

Truly your student.

'Over' is generally a preposition of movement, while 'above' is a preposition of location. I would say:

1) The sky is/ clouds are above me.
2) The sun is above me.
3) My plane was flying over the city of London.
