Difference between adjectives and adverbs.

When you need to describe something, we use adjectives or adverbs, it depends. When we want to describe a verb (say how the action has been made) we use adverbs; however, if we're describing a noun, we use adjectives. To know the difference between one and other and their correct use in each case, we've found these videos that will make a lot easier to understand it.

Also, there are several kinds of adverbs and adjectives.

There are descriptive adjectives, adjectives of quantity, possessive adjectives, interrogative adjectives and demonstrative adjectives. 

In the case of the adverbs, there are adverbs of time, adverbs of place, adverbs of manner, of degree or quantity, of frecuency, affirmative adverbs, adverbs of negation, interrogative adverbs and relative adverbs.
