Hi!  By definition, a preposition is a word that explains the relationship between 2 nouns.  

Ex1: The box is in your father's room. (explains a location) Other prepositions that explain locations include "from" "between" "on" "into," etc)

Ex2: The wallet of my friend is nice (explains ownership)

Ex3: I bought a gift for my sister's birthway (explains a purpose) Another preposition that explains a purpose is "to"

A preposition has not much meaning on its own.   It's only when it links two nouns together that the relationship is shown.

On the other hand, an adverb is a word that describes 1) a verb, 2) an adjective, 3) a complete sentence.
1) I smile happily ("Happily" is an adverb that describes "smile," a verb here)
2) The knife is extremely sharp. ("Extremely" is an adverb that describes the adjective "sharp.")
3) Fortunately, the little boy was saved. ("Fortunately" is an adverb that describe the whole sentence.)
Example 3 is a bit tricky because many people don't consider it as an adverb.  However, if you think about words like "therefore," "however,"  and "consequently," you will know that "fortunately" is an adverb.  BTW, "therefore" "however" and "consequently" are called Conjunctive Adverbs.

Finally, have a look at a sentence that my student created:

Unfortunately, the boy's father accidentally discovered his secretly kept girlfriend.  

Isn't it nice? He used all 3 kinds of adverb in one sentence!
