can anyone please explain this in simple words
IQueryable<t>

and
IEnumerable<t>

What I have tried:

i.e. for example
what is the difference between these 3

C#

IEnumerable<int> scoreQuery = //query variable
        from score in scores //required
        where score > 80 // optional
        orderby score descending // optional
        select score;

C#

var scorequery = from score in scores where score>80 order by score descending 
select score

C#

IQueryable<int> scoreQuery = //query variable
        from score in scores //required
        where score > 80 // optional
        orderby score descending // optional
        select score;
