I had a look into the Oxford Collocation Dictionary for the items COVER and COVERED and found the following examples:
The cars were all covered IN snow.
I was covered IN blood.
The children were completely covered WITH mud.
The path was now completely covered WITH thick snow.
Each body was covered BY a blanket.
After that, I felt some sort of uncertainty about which preposition to use in which specific situation and thought, that it might be rather helpful if native English speakers could cast some light of revelation upon the matter of how they feel it.
For example, firstly, I was intending to use a sentence The playground was covered by asphalt. But now I feel that all said prepositions may be used in it but with slightly different sense of meaning.
Is there any difference between the American and the British use?
