You might move boulders off of the seafloor cavern into a ship in order to examine the boulders. Often, this is accomplished using buoys that float the boulders from the seafloor to the ship.
You must learn strength. A HM used to move boulders.

You have to have strength...u get strength from saving a couple earlier on in the game..to teach one of your Pokemon strength you have to have a gym badge im not sure which 1 though..once you have that gym badge teach strengh to ur Pokemon and you will be able to move large boulders
The same way you got in, or use the escape rope or the move dig.
