The colors of the rocks that I have seen are white, black, and gray.

>> CORRECT

1. What is the difference between ‘keep’ and ‘keep up’?

If you mean just for simple comparison, like in this sentences:

She keeps hiding my charger. = ( usually followed by a verb)

She needs to keep up with the latest technology. = (usually followed by 'with' + object)

>> The word 'keep' has so many meanings depending on the sentence.

examples:

Keep the change. = (to hold in your possession)

Keep yourself warm. = ( to continue in the same situation for a long time)

I keep my keys in the drawer. = (put/store things somewhere)

Now, if we add a preposition after 'keep', the meaning totally changes. They are called phrasal verbs.

examples:

Keep up the good work. = ( continue doing well)

I can't keep up with my brother's running speed. = ( maintain a rate or pace with someone)

We need to keep up with the latest technology. = ( be updated with the changes)

2. Do I have to add an ‘s’ after ‘minute’ when it's ‘number + minute’?
-> ex) 30 minutes, 1 minutes, 10 minutes, 25 minutes

example:

I finished a 25-minute class. ( notice that there is an object after minute, so it is used as an adjective)

I studied for 25 minutes. ( talks about the length/how long someone studied)
