The sentence is not a preposition but, it does have a preposition in it: outside.
The term "outside" can be used as a preposition AND an adverb - depending on how the sentence is phrased.For example:I walked outside. (In this sentence, "outside" is an adverb because "I walked" can stand alone as an individual sentence.)Outside of the house, the winds roared. (In this case, "outside" is a preposition because the rest of the sentence cannot stand alone.)
There are no adverbs in this sentence. Mom = noun is = auxiliary verb waiting = gerund outside = preposition adverb for = preposition them = object pronoun. "outside" can be used as a preposition, but here it's an adverb

A preposition is a word that defines a relationship between a direct object (noun) and another noun, usually preceding the main verb. The object of the preposition is a noun being related. Ex. The cat (noun) went (verb) to (preposition) the store (object of the preposition) In this example the the nouns 'cat' and 'store' are being related. 'To the store' is an example of a prepositional phrase. Ex. Outside (preposition) my window (object of preposition), birds (direct object) sang (verb). In this example the prepositional phrase comes before the noun. While it is not the best example of effective syntax, it is not incorrect. The nouns window and birds are related by the preposition 'outside.'
