The Nazca lines (/ ˈ n ɑː z k ə /, /-k ɑː / [1]) are a group of over 700 geoglyphs made in the soil of the Nazca Desert in southern Peru. [ 2 ] [ 3 ] They were created between 500 BC and 500 AD by people making depressions or shallow incisions in the desert floor, removing pebbles and leaving different-colored dirt exposed. [ 4 ]
Nazca's temperatures range from 10 to 32 °C with an average daily high of 21 °C. Summer months from November to March are dry, sunny, and hot. During the winter from June to August, fog from the coast rolls over the hills to keep temperatures in the moderate range; however, the intense sun makes daylight hours seem hotter than they are. [3]
The Cocos–Nazca spreading centre (or the Cocos–Nazca spreading system) is the divergent boundary between the Cocos and Nazca plates. It extends from close to the East Pacific Rise northwest of the Galápagos Islands , to the southeastern end of the Middle America Trench offshore Panama .
Precipitation varies between none and 125 mm; daytime summer temperatures average 21.3 °C. To the north and south Cahuachi faces two pampas, or flat plain-like terrain: Pampa de San José and Pampa de Atarco, and on these plains is where the famous ground-drawings of the Nazca desert are found. The Río Grande region's soils are available for ...
AI-assisted research nearly doubles the number of known Nazca geoglyphs, ancient symbols formed in the ground by moving stones or gravel that date back 2,000 years.
Bathymetric map of area around the Galápagos microplate with main tectonic features marked. The 13,000 km 2 Galápagos microplate lies at the western end of the GSC. It is bounded to the west by strands of the East Pacific Rise, to the southeast by the Dietz Volcanic Ridge and the Dietz Deep rift, and to the north by the GSC. [4]
The Nazca culture flourished in the area from 200 BCE to 650 CE. [17] [18] The Nazca puquios are found along five of the nine named feeder streams into the Rio Grande de Nazca. From south to north, the rivers with puquios are Las Trancas, Taruga, and the Nazca, which has two tributaries, the Tierras Blancas and the Aja.
Map showing the location of Nazca Ridge off the west coast of Peru. The Nazca Ridge is a submarine ridge, located on the Nazca plate off the west coast of South America.This plate and ridge are currently subducting under the South American plate at a convergent boundary known as the Peru-Chile Trench at approximately 7.7 cm (3.0 in) per year.
