the Atlantic Ocean: We use the definite article "the" with names of oceans, seas, rivers, and deserts.

a randomly selected tall mountain: We use the indefinite article "a/an" when referring to a singular, non-specific item for the first time.

the ukulele: We use "the" when talking about the general skill of playing a musical instrument (e.g., "play the piano," "play the guitar").
