The Nazca Lines are a group of gigantic geoglyphs, etched into the earth as patterns or motifs in the coastal plain of Peru, about 250 miles (400 km) south of Lima. The Nazca Lines are best known for their representations of about 70 animals and plants, some of which are up to 1,200 feet (370 metres) long. A spider, hummingbird, cactus, monkey, whale, llama, duck, flower, tree, lizard, and dog are a few examples. How were they created? What do they signify? Thousand questions, 1 answer. Watch Un
