How did the Aztecs connect the island of Tenochtitlan to the rest of the valley?

The island of Tenochtitlan was connected to the mainland by three causeways that were located in the north, west, south regions of this city. Tenochtitlan was the capital city of the Aztec civilization.


What were the causeways of Tenochtitlan made of?

Tenochtitlan had causeways and bridges because it was built upon a lake. If it did not have causeways and bridges, the people would not be able to reach or leave the city. Not only that, but the bridges and causeways also helped them keep enemies out because bridges could be raised (or destroyed) and the causeways were narrow, preventing masses of soldiers to move into the city at a time.


Why did the Aztecs build their capital where they did?

Tenochtitlan was connected to the mainland by causeways leading north, south, and west of the city. These causeways were interrupted by bridges that allowed canoes and other traffic to pass freely. The bridges could be pulled away if necessary to defend the city. The city was interlaced with a series of canals, so that all sections of the city could be visited either on foot or via canoe.


What prevented enemies from getting to the city?

What did the Aztec use as transportation?

They built boats to travel across lake Texcoco from Tenochtitlan to the main land. They also built causeways or bridges to cross the lake.


Why were bridges and causeways necessary?

It is necessary because it helps the AZTEC to travel easier, and if an enemy tries to come they can move the bridge and they will not be able to go through briana corrochano
