What is the difference between a carrack and a caravel?

Third, few ships were well equipped for long ocean voyages or unfavorable winds. Explorers in the early 1400s used caravels-small, triangular-sailed ships built for coastal cruising. Over time, Atlantic sailors adapted caravels to handle square sails as well, making them better suited to wind conditions on the high seas. As voyages became longer, the need for bigger storage areas led to the development of a larger ship called the nao or carrack. By 1500 carracks might be as much as four times as large as caravels.
