What's the difference between present perfect tense and present perfectcontinuostense

[Harry12345]

What's the difference between present perfect tense and present perfect continuous tense?

For example:

I have been studying English for ten years.
I have studied English for ten years.



I have read the book since 2 hours ago.
I have been reading the book since 2 hours ago.


Thank you !

I have been studying English for ten years. (Began 10 years ago and is still studying)
I have studied English for ten years. (Began at some unspecified time in the past and is complete)

I have read the book since 2 hours ago.( "Since" is not usually used for duration but for a specific time/date. If you are still reading the book, you could say "I have been reading the book since 10 o'clock. OR "I have been reading the book for two hours." If you have completed reading the book, "I read the book two hours ago". OR "I finished reading the book two hours ago."
