The command:

in the specific case using -exec ls -l {} + invokes the ls utility with the -l option and operands specifying the names of one or more files (but limited to a number of operands that will not cause the invocation to fail due to an argument list too long error).

Using a semicolon instead of a plus sign to terminate the -exec primary will invoke the ls utility for each file instead of grouping a number of files together as operands to a single invocation of ls. (And, the semicolon has to be escaped or quoted, because it has special meaning to the shell.)
