What's the difference between A-Type game and B-Type game?

This question is about the NES Tetris, USA version.
In the main menu of the Tetris, you can choose between A-Type and B-Type. I know that it changes the ending (A-Type, B-Type), but am wondering if it has any other effects in the game.
Does changing the Type have any other effect in the game?
