Periglacial landscapes are not difficult places to build human structures because these landscapes are located in the cold climates not on the glaciers  surface. The main difference between Periglacial and glacial landscapes is that Periglacial are located on the rocky surface of earth having cold climate while on the other hand, glacial landscapes are located on glaciers where the surface is made of ice not rock so we can say that Periglacial landscapes are not difficult places to build human structures.
