The first photo shows a scale model of the tallest building of the world the Burj Khalifa and the second photo shows us the real Burj Khalifa, which is in Dubai, in the United Arab Emirates.
The two phtos are alike because both expose the same building, the first in a scale model and the second in real life.
The main difference between them is the height, while the first one is only a few centimeters long and the second one rises 828 meters.
Another difference is that the first one is made of cardboard and plastic because it is only a mini-representation of the second one, and this one is made with a lot of construction materials like metals, plastics, concrete, brickworks...
People can only live in the building of the second photo, while people can only watch the building of the first one.
I would like to visit the real building and watch the scale model, it would be a nice experience.
Nowadays the Burj Khalifa is the tallest building of the world but soon the Kigndom Tower, in Jeddah in Saudi Arabia will overcome the Burj Khalifa with his 1007 meters long.
It is happening what occured had ocurred with the curious case of the towers of San Gimignano in Italy, people want to have the tallest building and they compete to have it.
