The civilization of the Incas left a few mysteries to a new generation after his disappearance. One of them, we would like to present to you today. Deepening series of concentric terraces is located 50 kilometers north-east of the city of Cusco. Scientists believe that the Incas used this place as an agricultural laboratory.
Most large terraces are located in the center - they are huge in size and lowered to a depth of about 150 meters, leading to a round bottom. Six additional terraces in the form of an ellipse surrounded by concentric "heart" of morality. Above all this towering eight terraces, steps that capture only a portion of the perimeter.
Concentric terraces connected by numerous staircases, which are stone ledges, allowing people to move between the top and bottom of most of the bowl.
One of the most notable features of this place is the temperature difference between the upper and lower levels, reaching 15 ° C. Such a large temperature difference creates different microclimates. The effect is similar to the use of modern greenhouses. Perhaps the Incas thus studied the effect of different climatic conditions on crops.
It is no coincidence that the temperature difference between the levels of terraces corresponds to the natural difference between the coastal agricultural lands, which are at sea level and altitude agricultural land in the Andes at an altitude of 1,000 meters above sea level.
Moreover, pollen analysis of soil indicates that the soil from different regions of the Inca Empire were specially brought in Moray. Each contains a large central terrace soil of the region.
It is now believed that the terraces were used Moray Inca priests scientists to experiment with a crop of vegetables in order to determine what crops farmers should sow their fields throughout the Andean region.
Another mystery is how the system worked for the drainage of water flowing through aqueducts. The lower level, that is the bottom of the bowl has good drainage so that it never completely floods even during the heavy rains.
It is assumed that a paved terrace underwater channels that allow the outflow of water. Also, there is debate as to what is under the bottom of a natural porous stone structure which allows water to escape into the ground.
