Final answer:
The division of the word 'snow' can be understood as 'sn-' (onset) and '-ow' (rime) depending on the context, yet it is regarded as a single syllable.
Step-by-step explanation:
The word 'snow' can be divided into different units of sound or spelling depending on the context of the question. When discussing onset and rime, the word 'snow' is divided as sn- (onset) and -ow (rime). The onset is the initial consonant sound(s) before the vowel, and the rime is the vowel and any following consonants within a syllable. However, 'snow' is considered a single syllable because it only has one vowel sound that forms the peak of the syllable.
