Is zooming an adjective?

Oh no, Never!
zooming is a verb!
why?
well, first of all, verb mostly describes an action, for instance, eat, dance, jump, run, smile, all of these are verbs. If you add -ing to these verbs, they are still verbs. Same with the word zoom. It's a regular verb, and adding -ing to it doesn't mean its not a verb anymore.
