While adverbs basically express the way actions manifest themselves, prepositions mostly (but not exclusively) give information about the place and time in which a particular action takes place.
There are many prepositions in English, and some of them may almost act as if they were adverbs at times, but unlike adverbs, prepositions always need an object.
Prepositions connect different parts of the sentence adding information about time, place, direction, etc.
The majority of prepositions consist of a single word, but there are also prepositions which are the result of two or more words joined together to form sorts of idiomatic expressions like “apart from”, “according to”, “instead of”, etc.
Now, given that English prepositions are so many, for the moment, we are just going to see some of them, and give a couple of examples in order to observe how they actually work:
Prepositions of Time:
IN – “I’m going to take the exam in June.” – “She was born in 1985.”
ON – “I’ll see you on Sunday.” – “The earthquake happened on 15th June 2014.”
AT – “At Christmas, I will meet my uncles.” – “At New Year’s Day we are going to have a gorgeous party. Do you want to join us?”
UNTIL – “I will stay here until midnight.” – “Until now, our relationship has been pretty pleasurable.”
TO – “It’s twenty to midnight.”
FROM – “Today I’m going to work from 8a.m. to 13p.m.”
FOR – “I’ve known her for a very long time.”
BY – “By Friday, we must be able to begin.”
DURING – “He was suspended from school for persistently using his phone during a lesson.”
WITHIN – “She is going to give birth within a month.”
