Construction Materials

Heavy rainfall on steep mountain slopes causes landslides and erosion. To decrease the force of water, Inka engineers built terraces, with a sophisticated drainage system to control the flow.
Terracing was a sophisticated Inka technology, involving elaborate work below the surface.

Test Your Terrace
Now that you have added all the materials to the terrace, let's see if your terrace is stable.

CONGRATULATIONS
You've engineered a stable terrace just like the Inka.
After constructing the walls, the Inka filled the interior with a layer of rocks, a layer of smaller rocks, a layer of sand, and finally a deep layer of fertile topsoil.

Explore this panoramic image by swiping right or left. Look for the Inka terraces built into the steep hillside as well as the contemporary town of Pisac in the agricultural valley below. Near the town, look for the effects of erosion on the mountainside that does not have terraces.
