In the South American Andes, farmers have used terraces, known as andenes, for over a thousand years to farm potatoes, maize, and other native crops. Terraced farming was developed by the Wari culture and other peoples of the south-central Andes before 1000 AD, centuries before they were used by the Inca, who adopted them. The terraces were ...
The origin of terraces or andenes in the Andes is poorly understood, but they were being built by 2000 BCE. Agriculture became essential for the subsistence of a growing population after 900 BCE. People of the Huarpa culture and the later Wari culture (500–1000 CE) built terraces into the hillsides of the Andes in Peru. [4]
A series of terraces along a river. The oldest terraces (T1) are higher standing than the younger terraces (T3). The present floodplain (T4) will soon become the youngest terrace surface as the river incises. Terraces can be formed in many ways and in several geologic and environmental settings. By studying the size, shape, and age of terraces ...
Terraces were built to permit agriculture in the rugged terrain of the Andes. The heartland of the Inca Empire was in the high plateaus and mountains of the Andes of Peru. This area is mostly above 3,000 metres (9,800 ft) in elevation and is characterized by low or seasonal precipitation, low temperatures, and thin soils.
The oldest rocks in California date back 1.8 billion years to the Proterozoic and are found in the San Gabriel Mountains, San Bernardino Mountains, and Mojave Desert.The rocks of eastern California formed a shallow continental shelf, with massive deposition of limestone during the Paleozoic, and sediments from this time are common in the Sierra Nevada, Klamath Mountains and eastern Transverse ...

The Altiplano is an area of inland drainage lying in the central Andes, occupying parts of northern Chile, western Bolivia, southern Peru and northwest Argentina.
Sediments underlying fluvial terrace exposed in cutbanks along the Manú River, Peru. In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp".
