How did the religious structures built by the Inca differ from the religious structures built by the Aztecs?

The Inca built temples and shrines with finely-cut stones and precise construction techniques, such as at Machu Picchu. In contrast, the Aztecs constructed pyramids with stepped platforms to house their temples, like the Templo Mayor in Tenochtitlán. The Inca structures often integrated into the natural landscape, while Aztec temples were more monumental and centrally located in urban centers.
