Final answer:
The Italian Renaissance differed from the Northern Renaissance in its distinctive use of artistic techniques like frescoes, influenced by classical antiquity.
Step-by-step explanation:
The attribute of the Italian Renaissance that made it different from the Northern Renaissance is that the Italian Renaissance was known for artistic techniques, such as frescoes. While Renaissance humanism was present in both regions, the artistic climate in Italy was heavily influenced by classical antiquity and the desire to imitate the Ancients, leading to distinctive artistic expressions in forms such as frescoes, which are mural paintings made on freshly laid wet plaster with watercolors. The Northern Renaissance, however, developed distinct traits such as landscape and genre painting, closely linked to the region's evolving political landscape, especially in relation to the Protestant Reformation and nation-state formations.
