When the andes spat out this magma, these elements reacted rapidly with the oxygen in the air, which turned it into the color green. How the valle del arcoiris kept its colors green-colored rocks can sometimes be associated with copper, but the valle del arcoiris is one area of the atacama desert that is mostly devoid of this money-making metal.
The architecture of the andes can be divided roughly between highland and coastal traditions. Coastal cultures tended to build using adobe, while highland cultures depended more on stone. However, the lowland site of caral, which is currently the oldest complex site known in the andes, was built mainly using stone.

Concepts close to the elements now incorporated in plate tectonics were proposed by geophysicists and geologists (both fixists and mobilists) like vening-meinesz, holmes, and umbgrove.

A finite element template is a parametrized algebraic form that reduces to specific finite elements by setting numerical values to the free parameters. The present study concerns kirchhoff plate-bending triangles (kpt) with 3 nodes and 9 degrees of freedom. A 37-parameter template is constructed using the assumed natural deviatoric strain (andes).
The central andes and the atacama desert represent a unique geological, climatic, and magmatic setting on our planet. It is the only place on earth where subduction of an oceanic plate below an active continental margin has led to an extensive mountain chain and an orogenic plateau that is second in size only to the tibetan plateau, which resulted from continental collision.
It traces boundaries between several tectonic plates—including the pacific, juan de fuca, cocos, indian-australian, nazca, north american, and philippine plates. Seventy-five percent of earth’s volcanoes—more than 450 volcanoes—are located along the ring of fire.
